That is definitely good advice. I've run into this situation several
times. A machine had bad RAM that didn't seem to cause any problems
under "normal" operation. But, when trying to compile something large
like gcc, I would see non-repeatable segfaults (it wouldn't always
segfault at the exact same point). In those cases, I could often run
memtest for several passes and not see an error. But, _eventually_
ramtest would catch it. Run memtest for a few days. Really.
