Since I installed a new world and kernel on November 26 I'm seeing core dumps with cvsup, even though I reinstalled cvsup yesterday. Here the output from a gdb session without any debugging symbols: Core was generated by `cvsup'. Program terminated with signal 4, Illegal instruction.

Can't say for certain whether this is the culprit, but it looks suspicious to me. --- Gary Jennejohn
