I'd actually download your system vendor's memory diagnostic tool and run it in "No, really find the problem" mode, just to be on the safe side. I had a machine that had a one bit memory error that I didn't discover for years -- occasionally I'd see an odd segfault, but it turned out the page of memory usually got allocated to a bit of the kernel that didn't notice/care. Once in a while I'd recompile the kernel and the page would get used for something else, and turned up most frequently in Pine, and I would assume it was a Pine bug. I'd have saved myself a lot of trouble if I'd run the memory check the first time, so that's usually the solution I push on people now :-).
