             Bug #: 13384
           Summary: toplevel namespace aliases don't work
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com
    Classification: Unclassified


Consider this test:

namespace A {
  namespace B {
    namespace C {
      int x = 5;

      int nsfunc () {
    return x;
      }
    }
  }
}

namespace Q = A::B;

int xfun() {
  return Q::C::x;        // Breakpoint xfun
}

using namespace Q::C;

int yfun() {
  return x;            // Breakpoint yfun
}

int main(){
  return xfun() + yfun();
}

If you break in "main", then "break Q::C::nsfunc" should work.
However, it does not.

--- Comment #1 from Ben Longbons <b.r.longbons at gmail dot com> ---
This looks the same as the comment 5 of the duplicated bug (though an argument
*could* be made that that should have been a separate bug).

*** This bug has been marked as a duplicate of bug 7935 ***

--- Comment #2 from Keith Seitz <keiths at redhat dot com> ---
Actually, this is a different problem than 7935.

Tom wrote "break Q::C::nsfunc" should work -- and it does work with my
(recently submitted) patch for 7935.

However, I think what he meant to write is "break nsfunc" should work when
stopped in main, since we have imported Q::C. That does not currently work (and
my patch does not address this separate issue).

find_linespec_symbols and everything below it know nothing about imported
namespaces.

"b Q::C::nsfunc" doesn't work, but "Q::C::nsfunc()" does:
```
(gdb) b Q::C::nsfunc
Function "Q::C::nsfunc" not defined.
Make breakpoint pending on future shared library load? (y or [n]) n
(gdb) b Q::C::nsfunc()
Breakpoint 2 at 0x13f5f1604: file gdb-13384.cpp, line 7, column 9.
```
