             Bug #: 51527
           Summary: ICE: Segmentation fault: 'convert_to_integer' enters
                    infinite recursion
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal

         Component: c
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: g...@gcc.gnu.org

             Build: i686-pc-linux-gnu


== Code ==

void test_1 (void)
{
  int i;

  // notice it works with __uint24
  __int24 a, b;

  for (i = 0; i < 500; i++)
  {
      if (i & 1)
          a += 0x7654321L;
      else
          b += 0x5fe453L;
  }
