I have a Go program that's stuck in an infinite loop some where. Is there any way to force the program to print a stack trace, like it does when it encounters an error? I tried throwing several signals at it, but they only made the program terminate without printing a stack trace.

You should be able to get a stack trace by sending a SIGSEGV signal
(signal 11).
