 I would appreciate some patch nevertheless: the testcase presently just 
 ICEs, without any prior error message. Whether you make the testcase 
 compile properly or reject it with an error, I don't care, but anything 
 should be better than just an ICE!
 
 Giovanni: you asked about tests with older compilers -- your testcase ICEs 
 every compiler from 2.95 to 3.3. It works with 3.4, i.e. we get a proper 
 error message. Fixing the issue with the missing "template" allows 
 compilers since 3.0 to succeed, 2.95 still ICEs.

 I forgot to say: for the slightly reduced testcase I attached, there are 
 several error messages before the ICE. They are unrelated, though, and 
 have crept up while I tried to delete random stuff. It's the ICE at the 
 end we are interested in. Since the ICE already existed in the original 
 code, it's also not an error recovery problem.
