System: Linux kiste 2.4.0-test10 #20 Thu Nov 2 03:02:57 CET 2000 i686 unknown
Architecture: i686
GNU assembler 001002

Configured with: ../gcc-20001120/configure -enable-shared --disable-nls --enable-threads=posix --enable-long-long --enable-libstdcxx-v3
gcc version 2.97 20001120 (experimental)

>Description:
The following very simple code crashes the compiler with an internal
compiler error. This code is buggy, since it is an invalid template
declaration. 


>How-To-Repeat:
source file: tadt2.C

template<class T>
class A<T>;
