namespace bug using function templates

[John Pedretti <pedretti at roguewave dot com>]

Hi,

The following code does not compile, apparently due to a bug in the way
function templates and namespaces are handled: class templates seem to work
properly.

Thanks,

John

// foo.cc

namespace xx {
    // declare function template inside namespace
    template <class T>
    void foo (T&) { }
}

// using namespace xx;          // compiles if the using declaration is
moved to file scope

// declare function template inside global namespace
template <class T>
void bar (T& t) {
    using namespace xx;
    foo (t);
//    xx::foo (t);                       // compiles if foo() is explicitly
qualified
}

template void bar<int> (const int&);  // instantiate bar<int>
