Mostly yes, that's why I answered "by debugging the compiler". The compiler has no logic built in to analyse why it crashes. And in your case, it seems even the stack is corrupt.

Note that the AVR32 port is far from complete and probably still contains a multitude of bugs (even if you do get it to generate code, it's likely that it will be incorrect in many cases).
