Sorry to leave you hanging on the inline-perl list.

To be portable:
------------------------
/*#define DEBUG_PRINT*/

#ifdef DEBUG_PRINT
#define dbg_p(x) printf x
#else
#define dbg_p(x)
#endif

...
 free(p);
 dbg_p(("p free... DESTROY complete\n"));
...

Hmm.  How do you use a debugger on XS code?  If you know that, you're 
halfway there.  Then you just have to get Inline to not 
CLEAN_AFTER_BUILD.  As far as automagic c-level debugging support from 
within Inline, I don't think there's anything (though perldoc Inline::C 
makes some reference to an OPTIMIZE => '-g' setting for use with gdb.)
