            Bug ID: 16436
           Summary: pointed-to objects are not pretty printed
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python
          Assignee: unassigned at sourceware dot org
          Reporter: p.remmers at kabelmail dot de

Using eclipse CDT (Kepler) for debugging.

If there exists a pretty printer for a class, instances of this class are
pretty-printed ok. I.e. you can expand the variable in the "Variables" view and
see the pretty-printed children.

However, if the variable is a pointer to a class, then the pointed-to object is
not pretty printed. If you expand the pointer variable, you see the raw members
of the pointed-to object, not the children reported by the printer.

std::string str("Hello");  // pretty printed
std::string* pstr = &str;  // not pretty printed
