             Bug #: 57198

           Summary: ICE in warn_logical_operator for vectors

    Classification: Unclassified

           Product: gcc

           Version: 4.9.0

            Status: UNCONFIRMED

          Keywords: ice-on-invalid-code

          Severity: normal

          Priority: P3

         Component: c++

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: gli...@gcc.gnu.org





g++ crashes on the following program:



typedef int vec __attribute__((vector_size(4*sizeof(int))));

void f(vec* a, vec* b, vec* c){

  *c = (*a < *b) && (*b < *a);

}

includes a fix, but it is probably not the right place for that check if we

keep this code invalid.
