kernel oops in 2.1.105.

A user was compiling glibc-pre2.1-2.0.102 on my box, and it oopsed. cc1
segfaulted, and it appears the oops happened when the core was being written.
Of the progs I had running, pine segfaulted on quit, and bitchx segfaulted by
itself. There was another segfault on shutdown, and the disks weren't
unmounted. However, there were NO errors for e2fsck on the disk that the
compile was running on.

Kernel config and system.map are available on request. I do not know what
modules were in the kernel at the time. I do know that bttv, and sb were
insmod'd.

This system had compiled X several times during this uptime, so it can't be a
memory fault or heat problems.
