Jinoh Kang (@iamahuman) commented about dlls/ntdll/heap.c:
status = STATUS_NO_MEMORY; else if (block_size >= HEAP_MIN_LARGE_BLOCK_SIZE) status = heap_allocate_large( heap, heap_flags, block_size, size, &ptr ); + else if (!heap_allocate_block_lfh( heap, heap_flags, block_size, size, &ptr )) + status = STATUS_SUCCESS; else { heap_lock( heap, heap_flags ); status = heap_allocate_block( heap, heap_flags, block_size, size, &ptr ); heap_unlock( heap, heap_flags ); + + if (!status && heap->bins) + { + SIZE_T bin = BLOCK_SIZE_BIN( block_get_size( (struct block *)ptr - 1 ) ); + InterlockedIncrement( &heap->bins[bin].count_alloc );
Just to make sure: do we want to keep tallying even after the bin is enabled? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/1628#note_23093
