            Bug ID: 58814
           Summary: [4.7/4.8/4.9 Regression] ICE with volatile and
                    attribute vector_size
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following valid code snippet triggers an ICE since GCC 4.7.0:

====================================================
volatile int i __attribute__((vector_size(8)));

void foo()
{
  i += i;
}
====================================================

bug.cc: In function 'void foo()':
bug.cc:5:5: internal compiler error: in stabilize_expr, at cp/tree.c:3769
   i += i;
