If you happen to catch the infinite loop in action, either attach gdb to
the running process

    $ gdb <executable> <pid>

or cause a coredump

    $ kill -SEGV <pid>

to look at the post-mortem.  The former will provide you with greater
capabilities that might aid in debugging (e.g., you can call functions),
but, in a pinch, the latter should suffice.

I won't go into much more than that.  One could write volumes on the zen
of UNIX and the craft of debugging, but it's not appropriate, here.  Know
your tools.
