>Description:
G++ cannot parse complex class hierarchy.
The attached file triggers the error on gcc 2.95.
gcc 3.0 compiles it OK.

====command:
g++ -c error.cpp
====output:
error.cpp: In method `void SSS<IS,OS>::P()':
error.cpp:80: no class template named `SCTS' in `class ST<int,int,int>'
>How-To-Repeat:
see code in error.ii
command: g++ -c error.cpp
>Fix:
==== replace
typedef typename ST <vS, vS, vS> ::CO::I II;
==== with
typedef typename ST <vS, vS, vS> ::CO STCO;
typedef typename STCO::I II;
====
or just compile it with gcc 3.0.
But the problem is that gcc 3.0 cannot compile some other files and ICEs. (Like in my report c++/3728).
