>Environment:
System: Linux kiste 2.4.4 #38 Tue May 8 00:13:02 CEST 2001 i686 unknown
Architecture: i686
SuSE 7.1
glibc 2.2
GNU assembler version 2.11.90.0.4
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-long-long --enable-languages=c,c++,f77,objc
>Description:
The following illegal source code ts.C generates an internal compiler
error. If the template keyword is dropped in line 13 on the illegal
"template instantiation" the compilation does no longer crash.
>How-To-Repeat:
Source code ts.C
template <class T>
struct A
{
    void f(T) {}
};

template<>
struct A<int>
{
    void f(int) {}
};

template
void A<int>::f(int);

Compiling ts.C
g++ -v -c ts.C -W -Wall
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.0/specs
