 State-Changed-Why:
     With gcc 3.0.3 your example produces no internal compiler error, but the following compilation errors:
     
     a.cc:17: too many template parameter lists in declaration of `void foo()'
     a.cc:17: syntax error before `{' token
     a.cc: In function `int main()':
     a.cc:22: parse error before `;' token
     a.cc:23: `c' undeclared (first use this function)
     a.cc:23: (Each undeclared identifier is reported only once for each function it
