           Summary: Wrong namespace lookup for template function when
                    induced by a template parameter
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: nicolas dot burrus at lrde dot epita dot fr
                CC: gcc-bugs at gcc dot gnu dot org

This is a refinement of PR c++/11744 which was fixed the
2003-08-01. The bug is still present when the function call is
actually a call to a function template:

namespace nsp_foo {

  struct A {};

  struct foo {};

}

namespace nsp_bar {

  template <class T> // PR 11744 fixed the case where foo took
  void foo(T) {}     // a nsp_foo::A parameter.

  template <class T>
  void bar(T t)
  {
    nsp_bar::foo(t);
  }

}

int main()
{
  nsp_bar::bar(nsp_foo::A());
}

Here is g++-3.4 output:

namespaces.cc: In function `void nsp_bar::bar(T) [with T = nsp_foo::A]':
namespaces.cc:24:   instantiated from here
namespaces.cc:5: error: `struct nsp_foo::foo' is not a function,
namespaces.cc:12: error:   conflict with `template<class T> void
   nsp_bar::foo(T)'
namespaces.cc:17: error:   in call to `foo'

g++-3.3 and above, como and icc accepts this code.
