------- Comment #2 from jakub at gcc dot gnu dot org 2010-07-27 10:39 -------
One of these DW_TAG_variable DIEs at the DW_TAG_namespace scope is created
from declare_in_namespace when processing decls_for_scope of a lexical block.
The other one comes from declare_in_namespace from dwarf2out_global_decl
from wrapup_globals_for_namespace.
The problem is that the C++ FE doesn't unify externs, so the debugger sees
different decls with the same name, but different DECL_UID.
So for say
namespace N
{
int i;
void foo (void)
{
{ extern int i; i++; }
{ extern int i; i++; }
{ extern int i; i++; }
{ extern int i; i++; }
}
}
there will be 5 DW_TAG_variable DIEs in DW_TAG_namespace.
