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. -- Grant Edwards grant.b.edwards Yow!
