This set of symptoms arises frequently. Typically, the
problem is an uninitialized variable. Such a variable has
a random value when you run it normally, but the debugger
may happen to zero-initialize it, making the program seem
to work.

Try to reduce the program to a tiny testcase that reliably
reproduces the problem. Once you've eliminated everything
that's not the problem, you'll probably see it.

Alternatively, try using a 'malloc debugger' such as
mpatrol. Or add lots of runtime assertions to check sanity
at every step. Or try using a map file to find where the
problem is, and backtrack from there.
