Preprocessed output from the source causing the ICE.

The initial bug creation doesn't seem to allow attachments. :)

Which is fixed in bugzilla 3.0 which we will be updating in the near future.
Comment 3 Andrew Pinski 2007-04-18 00:09:41 UTC 
Reduced testcase:
class Collision {
   int edge;
   int triangle;
  float _M_instance[3] __attribute__((__aligned__));
};
void  get_collisions(Collision a) {
  Collision b = a;
}
Comment 4 Andrew Pinski 2007-04-18 00:42:08 UTC 
We try to get a type for size of 128bits which is TImode.  And on x86, TImode is not supported.
