dmalloc works by intercepting the *alloc calls and using its own
functions, i suspect this is causing problem becasue stdlib.h is trying to
do the same thing.
If stdlib.h redefines *alloc to *alloc_leap then dmalloc wont see them if
it tries to redefine them afterwards... which i think make sense if you
are #including <stdlib.h> prior to #including <dmalloc.h>.... could be
worth a try reversing the order, including dmalloc.h first.
(i dont know c++ so i could be totally wrong).

The info page has a small section relating to usage with c++, apparently
your supposed to compile and link dmalloc.cc with the program your trying
to debug, it intercepts c++'s new and delete functions.
