Normally, i'd say extract the name list and look for the symbols
around the faulting instruction pointer, but...

...this rather smells like a hardware problem. Try relaxing the
conditions for your RAM/cache (or EDO) RAM etc., or try to make the
cache write-through. There are ASUS boards known to have a broken
chipset, but i've forgot which one.
I assume every memory-expensive program would cause this, the compiler
is only just the best known expample. Try troffing a large .ms file,
i guess you'll experience the same.
