Confirmed ICE with gcc-3.4.5 also.

This is what 4.1.0  says:
error.C:4: error: ISO C++ forbids declaration of 'T' with 
no type
error.C: In instantiation of 'segfault<test>':
error.C:7:   instantiated from here
error.C:4: error: invalid use of undefined type 'class 
test'
error.C:7: error: forward declaration of 'class test'
