According to Cobb, Brian:

It's dying in a deconstructor in the standard C++ library, so unless
htdig is seriously stomping on memory somewhere (unlikely if all it's
done is read the config file), this seems to point to a problem in the
library, or kernel, or an incompatibility between them.
If you didn't upgrade your C++ and/or C libraries when ungrading your
kernel, it may be that some kernel bug or incompatibility was introduced.
Check to see if a library update is available, and relink with it.
If you're already running a newer library, it may be a bug was introduced
there. Are your runtime and development libraries the same versions?

Not much hope of this being in the FAQ. It's the first time I've seen
such a problem. Good luck getting to the bottom of it.
