The attached invalid code causes an ICE on svn trunk. It passes on g++ 4.4.3

The error I get is:

caj@nyanko:/dev/shm/clang-fuzzer$ /gccsvn/bin/g++ t.cc
t.cc:3:137: warning: missing terminating " character [enabled by default]
t.cc:3:1: error: missing terminating " character
t.cc:3:20: error: two or more data types in declaration of
‘parameter’
t.cc:3:135: internal compiler error: in tsubst, at cp/pt.c:10121
Please submit a full bug report,
with preprocessed source if appropriate.

It would be more correct to say that it doesn't ICE on g++ 4.4.3, but still
error-recovery is awful:

pr44623.ii:3: error: missing terminating " character

pr44623.ii:3: error: expected '}' at end of input

This seems to have gotten fixed.
