You could try adding TRACEs near where local_buffer is used to see if/when its value changes.
The value of This->local_buffer looks the same both before and after. But on at least one occasion, the first Heap warning looked like this:
err:heap:HEAP_ValidateInUseArena Heap 0x110000: in-use arena 0x1ed328 next block 0x1f5038 has PREV_FREE flag 5e
