I've often been able to flush out difficult bugs by compiling on another platform.

Back in the bad old DOS days, I quickly learned to develop the programs on a 
protected mode operating system, then port to 16 bit real mode DOS as the last 
step. :-)

Memory corruption bugs show themselves differently on different platforms, and 
one of them likely will make it easier to find the bug.
