Something scary for halloween

[brooksmoses]

So, I discovered something scary this evening, as appropriate for the holiday. (Well, scary, for those of you who know C++, anyhow.)

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":

A template 14 layers deep?

Luckily, you can find some utilities on the web which will decode C++ compiler error messages that contain templates.
