           Summary: function lookup class should not depend on its linkage

           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++

struct S {
  static void m (int x) {}

template<void (*T) (int)>
struct K {
  void f () { T (0); }
};
int main () {
  K<&S::m> k;
  k.f ();
}
------------------------------------------------------------------------------
K<&S::m>::f (this=0x7fffffffdc9f) at tmplmembernot.C:6
6      void f () { T (0); }
(gdb) p T
No symbol "T" in current context.
(gdb) ptype T
No symbol "T" in current context.

expected:
(gdb) ptype T
type = void (int)
 - `print T' is another problem - GDB PR c++/12933

cp_lookup_symbol_imports_or_template uses namespaces from
`SYMBOL_NATURAL_NAME (function)' which may come demangled from
DW_AT_linkage_name and it may not match parent
DW_TAG_structure_type->DW_AT_name such as due to:
