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
GCC build triplet: i686-pc-linux-gnu
GCC host triplet: i686-pc-linux-gnu
GCC target triplet: i686-pc-linux-gnu
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.

I can confirm this on the mainline (20030805).

Looks like the same patch that broke PR 11744 broke this one too.

------- Additional Comments From bangerth at dealii dot org 2003-08-05 18:21 -------
Confirmed. Here's a cleaned-up example:
--------------------------
namespace NS_1 {
struct A {};
struct foo {};
}
namespace NS_2 {
template <typename T> void foo(T);
template <typename T>
void bar() {
NS_1::A a;
NS_2::foo(a);
}
template void bar<int>();
}
---------------------------
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
x.cc: In function `void NS_2::bar() [with T = int]':
x.cc:15: instantiated from here
x.cc:3: error: `struct NS_1::foo' is not a function,
x.cc:7: error: conflict with `template<class T> void NS_2::foo(T)'
x.cc:12: error: in call to `foo'
gcc seems to think it needs to do Koenig lookup, but this is unnecessary
here since the call to foo is namespace-qualified.

I verfied that the patch that broke 11744 also caused or exposed this
regression, by using the cleaned-up test case from comment #2 with
versions of cc1plus built just before and after that patch on
i686-pc-linux-gnu.

PR 11828 may or may not be a duplicate, but it at least looks very much
related. Whoever comes around to fixing this one should look at the
other one as well.
