             Bug #: 13615
           Summary: inherited typedefs not found properly
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com
    Classification: Unclassified


Consider this program:

struct Base {
  typedef int value_type;
};

struct Derived : public Base {
  value_type x;
};

Derived d;
Derived::value_type v;


Compile this with '-g -c' and run gdb on the .o.
Now some type lookups work, but some do not:

(gdb) ptype Derived::value_type
type = int
(gdb) p (Derived::value_type *) 0
A syntax error in expression, near `) 0'.
(gdb) p (Base::value_type *) 0
A syntax error in expression, near `) 0'.
(gdb) python print gdb.lookup_type('Derived::value_type')
Traceback (most recent call last):
  File "<string>", line 1, in <module>
RuntimeError: No type named Derived::value_type.
Error while executing Python code.
(gdb) python print gdb.lookup_type('Base::value_type')
Base::value_type
