After rebooting, it appeared that the last build the box was running
(gcc-3.4) didn't complete, though the box was actually idle when it died
(according to mrtg reports). For the records, i've seen my glibc build
get stalled (ie: the box gets idle and no progress is made) in the test
suite a little before gcc was being built.

So, on the same box after a fresh reboot, trying to "du -sh" an unclean
gcc-3.4 build directory (i tried twice) made du to segfault and dmesg to
show the following (note, i tried du on other stuff and it worked
without problem):
