What I do is have a script that extracts the relevant lines from gdb.sum
and normalizes them; then I compare the normalized files.
Our buildbot automates all this -- but I suspect somewhat poorly,
because Jan is constantly finding regressions I didn't see.
Probably we should all use his script. I think he's sent it to one of
the lists before; or maybe it is on the wiki.

The most common approach is to learn what they are and ignore them.
This isn't totally satisfactory; fixing them or removing them would be
nicer.
