Notice that the ICE happen only with checking enabled, but seems easy to fix
and we can avoid "confused by earlier errors, bailing out" otherwise.

Hi Paolo,

the testcase g++.dg/parse/crash25.C is hosed:

// PR c++/20536
// Found by Wolfgang Wieser 03/2005.
// { do-do compile }
  ^^^^^^^

This should be dg-do, right?
Could you please fix that?
