break_memory_alloc take as an argument concrete allocation index and it should
break at this particular allocation. We may consider designing interface which
will support breaking *next* allocation, but it's not there yet.

Note that in both cases you actually do not know where the allocation occurs.
The primary usage of this functionality is to help with memory leaks detection.
