 krister mentions that inserting a useless move after the label also
 avoids the problem:
 
 --- a/external/gpl3/gcc/dist/gcc/config/vax/builtins.md
 +++ b/external/gpl3/gcc/dist/gcc/config/vax/builtins.md
 @@ -70,6 +70,7 @@
    emit_jump_insn (gen_jbbssi<mode> (operands[1], const0_rtx, label,
 operands[1]));
    emit_move_insn (operands[0], const0_rtx);
    emit_label (label);
 +  emit_move_insn (operands[0], operands[0]);
    DONE;
  }")
 
 And that it's related to an optimization from the label being the last
 thing in the function
