             Bug #: 51768
           Summary: [4.5/4.6/4.7 Regression] ICE with invalid asm goto
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: ice-on-invalid-code
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: ja...@gcc.gnu.org


void
foo (void)
{
  asm goto ("" : : : : lab, lab, lab2, lab);/* { dg-error "duplicate asm
operand name" } */
lab:;
lab2:;
}

void
bar (void)
{
  asm goto ("" : : [lab] "i" (0) : : lab);/* { dg-error "duplicate asm operand
name" } */
lab:;
}

ICEs with tree-checking (or just crashes during error reporting if not tree
checking).
