             Bug #: 52935
           Summary: Unnecessary DW_TAG_pointer_type DIEs in C++
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: debug
        AssignedTo: jason@gcc.gnu.org
        ReportedBy: jakub@gcc.gnu.org


struct S { struct S *a; }; struct T { struct S *b; } t;
has two DW_TAG_pointer_type DIEs with the same attributes, one is referenced
from within DW_TAG_structure_type S members, while the other one for other uses
outside of the class.
Jason said last night this is because of of the injected-class-name.  Would be
nice to get the debug info right (as compiling with C instead of C++ does).
