Hi,
I've committed the attached patch fixing the following testsuite fails
on s390 (-march=z196):
< FAIL: gcc.dg/pr48335-2.c (internal compiler error)
< FAIL: gcc.dg/pr48335-2.c (test for excess errors)
< FAIL: gcc.dg/pr48335-3.c (internal compiler error)
< FAIL: gcc.dg/pr48335-3.c (test for excess errors)
I've also committed the fix to 4.8 branch since it is a regression
from 4.7.
Bye,
-Andreas-
