I got three oops (enclosed) while doing C compilations. I used a script
which performed the same compilation four times (with different
settings). The source files were on remote (NFS) partition while the
objects were produced to a local directory.
I didn't got ksymoops to work (wrong C++ libraries?) so I did it
manually. The last two Oops were propably caused when kernel was
recovering from the first one (killing the process).
