A testcase (foo.c)

This is the bad input which causes gcc 3.3.2 to dump core.

Confirmed with 3.3.2-prerelease and 3.4. This is a regression from 3.2.
The trigger is a missing ")" in a macro invokation.

Do any of you think this worth fixing in 3.3.x?

Yes, I do.

I will look at this, but I would really appreciate a reduced testcase if possible.

I spent a little time chopping things out of the test case. It seems to be 
very sensitive to the size of the file. I gave up after chopping 20 KB out of 
the file.

I'm going to make a pre-release within two days, do you
think you'll have something ready by then?

I cannot reproduce this problem in GCC 3.4.0.

Is there a more reliable way of reproducing it?

In any case, I'm retargeting this at 3.4.1.

Gaby and I have already agreed that the 3.4.x target milestones take precedence
over the 3.3.x milestones.  Gaby, please note that this used to be marked as
targeted at 3.3.4, but is now targeted at 3.4.1.

IIRC this one was fixed already...?

Has nothing to do with the c-decl.c rewrite, just for the record.
