[danglin at gcc dot gnu dot org]

------- Comment #3 from danglin at gcc dot gnu dot org  2008-01-06 21:35 -------
This bug is present on 4.2 branch but head doesn't fail for me.  The problem
is a deleted label.

Breakpoint 1, output_operand (x=0x4be5a208, code=0)
    at ../../gcc/gcc/final.c:3171
3171      gcc_assert (!x || !REG_P (x) || REGNO (x) < FIRST_PSEUDO_REGISTER);
(gdb) p debug_rtx (x)
