	Here is the relevant code from dwarf2out.c:8720:

 >   /* When optimization is enabled (via -O) some parts of the compiler
 >      (e.g. jump.c and cse.c) may try to delete CODE_LABEL insns which
 >      represent source-level labels which were explicitly declared by
 >      the user.  This really shouldn't be happening though, so catch
 >      it if it ever does happen.  */
 >   if (INSN_DELETED_P (insn))
 >     abort ();


	If you need any more info, let me know.
