--- Comment #23 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
There is some one more non-escape failure with the protobuf sources. I am
trying to reduce it right now. 

The IR looks like:
```
  google::protobuf::internal::TcParser::Error.constprop.isra (msg_55(D), _227,
hasbits_67(D));
  goto <bb 90>; [100.00%]
...

  <bb 90> [local count: 82179106]:

  <bb 91> [local count: 1073739452]:
  # _35 = PHI <_89(5), 0B(90), _141(85), ptr_31(76), ptr_32(79)>
  return _35;
```
