Of course.
But on PPC you *usually* get zeroes, which allows uninitialized
variables to exist as silent bugs. That's a Bad Thing.
The Intel implementation (and apparently Rosetta) pretty much never give
nice clean zeroes, making the bugs show up and get fixed. Which is a
Good Thing, except for the frustration of tracking down stupid mistakes.
Of course no one else has any code with such amateur-hour mistakes as
uninitialized variables. Right?
