The bug is fixed in GCC 4.4.0.
(Because -ftree-parallelize-loops was introcuded in GCC 4.3.0,
the crash in GCC 4.3.x is not a regression.)

--- Comment #15 from reichelt at gcc dot gnu dot org 2009-11-09 21:42 --- The bug is not a regression, because the code snippet is invalid and was never correctly rejected since the introduction of __builtin_offsetof.

Confirmed. Even shorter testcase (crashes with -O2

==

{

};
int foo();
A bar(double x)
{
double y;

y = 1 / x;
return y;
}
==
bug.cc: In function 'bar(double)':

Please submit a full bug report, [etc.]
The code compiles with GCC 4.4.0, but crashes since GCC 4.4.1.
