[PATCH] Fix crash27.C and crash29.C testcases

[Mark Mitchell]

Ugh.  

This is why we are writing a new parser.  Of course, that won't help
before 3.0.  I'm somewhat tempted just to ignore these kinds of bugs
for 3.0, rather than complicate the code with a lot of gunk that we'll
then want to remove later -- but that's perhaps irresponsible.  It
would be great if Jason Merill would comment.
