As it always seems to be just one bit flipping, it could also be hardware-related memory corruption.

I once had similar problems with very strange things happening occasionally.  At first, problems only occurred very seldomly, then more and more often. After quite a bit of hunting in the wrong places, it eventually turned out to be the power supply slowly getting flaky (voltage slowly dropping, and having more DC ripples than allowed).

So, if you can take the machine down, run a memory tester (such as memtest86).

Also, have maybe other strange things been happening on the machine?  For example, compiling huge programs has always been a good (indirect) "memory test" for me, as compilers tend to be quite sensitive to corrupted memory, and usually randomly crash as a result...
