Ack! Core dump when committing...

I was trying to commit Billy's fixes for mixed-case table names and have
a problem! cvs is core dumping when I try to commit psql.c. I can commit
other files just fine (or at least did before running into this). The
problem is on the REL6_4 branch, and I succeeded in committing the same
patches to the main branch before running into this problem.

I tried brute-force removing the locks and retrying but get the core
dump repeatably. I've left the locks in for now until we have a fix.
btw, the cvs file is pretty big, but I don't know if that has anything
to do with it. Any suggestions?

If it helps, I have a local copy of the cvs tree on my machine (from
CVSup) and perhaps that would be a good backup copy for the psql.c
archive file??
