That invalid read in HEAP_FindFreeBlock seems like a heap valgrind annotation
problem, not a normal use-after-free.
The block it finds was created when HeapReAlloc shrank a block, and its
metadata was marked accessible than. Maybe I'll log all the mark_* calls,
and write a script to check to see if any of them marked that particular
metadata inaccessible.
