If it's not reproducible, it's certainly a hardware fault, since
there's no randomness in gcc that could cause such differences.  But
if the results are reproducible on both machines, it could be some
memory management problem in gcc, that is triggered by the code you
posted and some minor differences in system header files, for example.
But, if you don't post the preprocessed code, it's hard to tell.
