------- Comment #7 from rguenth at gcc dot gnu dot org 2007-08-22 10:07 -------
Is the following valid?
typedef int IA[];
typedef int A5[5];
typedef int A10[10];
A5 array5;
A10 *ap;
void
f (void)
{
int ap;
{
extern IA *ap;
ap = &array5;
}
}
The real problem is that the frontend creates a conversion to (int[] *) rather
than (A5 *) which is the type of ap at gimplification time. The patch
doesn't address this, but merely forces the conversion to (int[] *) which is
there also without the patch.
