I'm wondering if one does a ton of these cache-bypassing stores whether something gets hosed because of that. Not sure what that could be though. I don't imagine the chipset is involved with any of that on the Athlon 64 - either the CPU or RAM seems the most likely suspect to me


The glibc version is essentially the "perfect" copy function for the
CPU. If you have any bus/memory problems or chipset bugs it will bite
you.

Anyone have any suggestions on how to track this further? It seems fairly clear what circumstances are causing it, but as for figuring out what's at fault..
