i had a question here but i seem to have answered it, so i thought i'd
share...
memory leaks are really annoying. and they're also tough to spot.
glibc provides a method to spot them:
#include <mcheck.h>
and then call mtrace() at the start of main(). compile the program with
-g for debugging, and set the environment variable MALLOC_TRACE to a
file to log memory allocation and freeing. once you've run the program
run this:
mtrace <program> $MALLOC_TRACE
voila, it lists all the memory leaks and the lines where the memory was
allocated.
dunno if this works from c++, but then c++ programs are supposed to leak
like a sieve anyway so does it really matter?
