I've done it, I think more than once.

I was getting to a point in the code. I could tell by a log statement or some such. But I didn't know in what circumstances I was getting there - what path through the code. So I put in something like

  char *p = 0;
  *p = 1;

in order to cause a core dump. That core dump gave me the stack trace, which let me see how I got there.

But I never checked that in. If I did, I would expect a severe verbal beating at the code review. Even more, it never made it into release.
