The mimalloc version v1.7.3 and v2.0.3 have much improved support for macOS -- perhaps this also fixes the problem on iOS?
@daanx i just tried v2.0.3 on iOS15
if MI_OSX_ZONE + MI_OSX_INTERPOSE are turned on, the zones crash upon application boot:
but if you turn off MI_OSX_ZONE and leave MI_OSX_INTERPOSE on, the application boots properly and it seems to finally work now!
Edit: this is via linking the object file
Ah it is great to hear that it starts working on iOS :-).
But those malloc_zones are a never ending source of trouble :-(. The zone_size definition in the debugger, is that the one from mimalloc (in alloc-overrride-osx.c) ?
I see I defined it as:
static size_t zone_size(malloc_zone_t* zone, const void* p) {
MI_UNUSED(zone);
//if (!mi_is_in_heap_region(p)){ return 0; } // not our pointer, bail out
return mi_usable_size(p);
}
Can you comment out the line that checks if it is a valid pointer and see if it starts working? I was perhaps a bit too positive there :-)
if i uncomment out that line, then the program doesn't finish booting... failing in zone_size still via realloc.
and with MI_OSX_ZONE=OFF, i'm now getting one weird EXC_BAD_ACCESS when calling some iOS library function, via...

@daanx if you provide with a "How To" / any architectural knowledge needed i can fully debug it myself and then push a PR. rather than these back and forth haha. just need a point in the right direction.
turning on debug mode instead of EXEC_BAD_ACCESS it halts on an assertion
mimalloc: assertion failed: at "/xxx/libraries/mimalloc-2.0.3/src/alloc.c":75, mi_heap_malloc_small
assertion: "heap->thread_id == 0 || heap->thread_id == _mi_thread_id()"
