mlibc panicked at Assertion '!"slab_pool corruption. Possible write to unallocated object"' failed!.

If a rear guard is placed (i.e all malloc calls allocate size + 16) it works. So its most likely an out of bounds access.

This issue is too generic: there may be multiple different OOB writes happening inside different parts of mlibc and triggered under different circumstances. Can you mention how you triggered the issue?

it's also extremely unlikely to be in mlibc (or rather, in mlibc in isolation; what program did this? what's the backtrace? etc)
