Comment (by anevilyak):

 Replying to [comment:4 ttcoder]:
 > I wonder if there is a way I could set a "watchpoint" in Debugger on a
 given heap area (rather than watch a given variable).. If yes then,
 knowing in advance one of the addresses of leaked memory blocks (from a
 previous run with printf() debug output ..etc) I could invoke debugger()
 at the beginning of main(), set the watchpoint on that address, click
 "Run" and get immediately notified (with an explicit backtrace) when that
 memory block gets malloc()ed. If I know who malloc()s it I'll have a good
 lead on who should be free()ing it yet fails to, probably.

 You can set such a watchpoint ; when you right click -> watch, the
 resulting dialog just prepopulates the address of the variable, but you're
 free to change that to an arbitrary address. However, that won't do you
 any good here, Haiku uses address space layout randomization, so the
 addresses will not in any way be predictable between runs.
