             Bug #: 56131
           Summary: [4.8 regression] gcc.dg/pr56035.c ICEs gcc on
                    sparc-linux
    Classification: Unclassified
           Product: gcc
           Version: 4.7.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: regression
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mikpe@it.uu.se


The recently added gcc.dg/pr56035.c test case fails on sparc-linux:

+FAIL: gcc.dg/pr56035.c (internal compiler error)
+FAIL: gcc.dg/pr56035.c (test for excess errors)

Compiling it with an x86_64-linux to sparc-linux cross-compiler shows:

> /tmp/objdir/gcc/xgcc -B/tmp/objdir/gcc/ -O1 -ftree-vectorize -fcse-follow-jumps -fstrict-overflow -S pr56035.c 
pr56035.c: In function 'f':
pr56035.c:35:1: internal compiler error: Segmentation fault

This ICE is different from the one in PR56035.

Reverting the PR56035 fix in r195462 makes no difference.

gcc-4.7 does not ICE on this test case.
