Ooops, I just wrote:
#define IN_MY_TEXT(addr) ((void *) &start <= (addr) < (void *) &etext)
                                          ^^^^^^^^^^^
#define IN_MY_HEAP(addr) ((void *) &end <= (addr) < (void *) sbrk(0))
					^^^^^^^^^^^

You need of course separate comparisons here
like in:
	((void *) &start <= (addr) && (addr) < (void *) &etext)

As I said the code wasn't tested, even not reviewed enough. sorry.
