While testing Battlefield: Bad Company 2, I saw a glibc memory corruption error,
so I ran with +heap,+relay,+d3d. That showed
err:heap:HEAP_ValidateInUseArena Heap 0x110000: block 0x13ef80 tail
overwritten at 0x13ef85 (byte 0/11 == 0x40)
Inspection of code before the block in question was allocated led me
to the lines
newArray = HeapAlloc(GetProcessHeap(), 0, sizeof(*newArray) *
This->num_contexts + 1);
newArray[This->num_contexts] = ctx;
which seem to be missing some parentheses.
Sure enough, the attached patch got rid of the heap error.
