The following invalid code snippet triggers an ICE since GCC 4.2.0:
=================================
void foo(int i)
{
extern int a[i];
#pragma omp parallel
a[0] = 0;
}
=================================
bug.c: In function 'foo':
bug.c:3: error: object with variably modified type must have no linkage
bug.c:3: error: storage size of 'a' isn't constant
bug.c:6: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
