Which is what I suspect.

All I know is that the machine passes memtest86 with flying colors and
a clean install on a different disk seems to work.

I've used memtest86 on other machines to find problems. This time
when I ran it, there were no problems.

If you read my bug report, you would notice that I was able to do a
clean install and proceed without problems -- performing the same
tasks under the same load conditions.
I've performed many tests to verify that this is not a hardware
issue. Further, if it were a hardware issue, it is strange that two
separate machines would show the same behavior at the same time
(i.e. after upgrading glibc) and that the buggy behavior disappears
after a clean install.
Note that mounting the old disk in the rebuilt system and using it for
a chrooted environment fails to reproduce the problem. So, I thought,
"perhaps a corrupted kernel" and used dpkg --root=/mnt to install a
new kernel on the old partition. Yet, the problem is still there if I
boot from the old partition after doing this.
Note that I'm reasonably sure that the configuations of the new
install and old install the same. I used jablicate to generate a
