Ha, that is good to see! In some of our services v3 reduces memory usage by _a lot_, but on many small benchmarks the difference is usually less pronounced. On...

Thanks! I will take a closer look and improve it. Btw. thanks for your previous suggestions which have improved mimalloc. ps. I don't want to derail your current effort to...

Thanks -- something strange is going on as v3 should not be _that_ much slower. What platform are you using? Is this v3.1.5 ? I rewrote the test in C++...

Ah, this is starting to look rather complicated and it is unclear whether we actually need it. Currently, it is only called if we cannot do it directly and via...

Thank you for the report -- I hope we can fix this. I just searched for Qt and custom allocators and found some benchmarks [1] by @vohi where he compared...

Ah great to hear that. Mmm, not sure _why_ though :-) There must be some interaction where some type of object is allocated by a custom allocator in Qt (say,...

Thanks! a small test case would be great if you can manage that. I wonder if we "miss" a `new` overload that Qt defines, and than one of our `delete`...

Hi, it looks indeed like a pointer mismatch -- which probably means the dynamic override is not working as it should. Can you try to build mimalloc in debug mode?...

Apologies for the late response. Yikes, I didn't know jemalloc was getting archived -- that's unexpected :-( Anyways, I am quite interested in USDT's but I would have to study...

Ah, very interesting. Yes, that is definitely it. Hmm, the aligned hint is behind a `#if MI_INTPTR_SIZE >= 8` -- you could add there a "not riscV" to disable hinting....
