templated friend ostream & operator <<

[zvyagin@gams.ihep.su]

Dear gcc developers!

The code (see below) compiles fine with egcs-1.1.2 and does not compile
with gcc-2.95.

I get error message:
bug1.c: In instantiation of `A<int,6>':
bug1.c:15:   instantiated from here
bug1.c:8: template-id `operator <<<>' for `operator <<(ostream &, const
A<int,6> &)' does not match any template declaration
bug1.c: In function `int main()':
bug1.c:16: no match for `_IO_ostream_withassign & << A<int,6> &'
... more lines ...


With best wishes,
Alexander Zvyagin.
