I had the reverse problem once: my program would seg-v if I threw -debug.

I think I eventually nailed it down by using writeflns to determine
where abouts the crash was happening (actually before main() got
called), then slowly removing debug {}, in {}, out {} and invariant {}
code until it stopped.

Turned out I was asserting a property of an object whose reference was
null; silly me.

The other thing you can do is load the program up into ddbg (if you're
on Windows; otherwise, try another debugger) and see if it will tell you
where you're segfaulting.
