The fact that it was failing in a different place each time is a very strong indicator that it was hardware-related: compilers are pretty deterministic beasts in what they do; given the same input they will go through the same set of steps and produce the same output. If this was a bug in gcc, I'd expect it to fail in the same place each time when it tries to compile the magic code. Perhaps what you're seeing is a hardware fault which is only triggered by the particular combination of instructions output by gcc with -march=3Dk6, but I think the evidence is pretty strongly in favour of a hardware fault of some kind.
