I was tracking down a segfault in a testcase for our rather heavily template-based C++ library, and decided that the obvious thing was to run it in GDB and have a look at the stack trace.

I present to you just a tiny -- but telling -- piece from the middle of the ten-thousand-character result I got from "where":
