3.4 with new parser
>Description:
This is a new ICE on this little illegal piece of code:
--------------------------------
template <class T>
typename O<T>::I f () {}
--------------------------------
Since O is not a declared class, this should fail, and
indeed does with 3.3:
deal.II/base> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -c d.cc
d.cc:2: error: parse error before `<' token
However, with 3.4 I now get
deal.II/base> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c d.cc
d.cc:2: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
What's a little annoying is that the ICE happens before
any message is written, so it is not obvious right away
what's wrong.
