  19 # This contains tests for GDB's use of RTTI information.  This stems
  20 # from a bug reported in PR gdb/488 and other places, which leads to
  21 # statements like 'warning: can't find class named 'C::D', as given by
  22 # C++ RTTI'.  It arises from GDB not knowing about classes that are
  23 # defined in namespaces.
  24
  25 # NOTE: carlton/2003-05-16: I suspect it could arise from nested class
  26 # issues, too, and even once we fix that, there might be situations
  27 # (involving templates, in particular) where this problem triggers
  28 # because GDB and GCC have different ideas what a class is called.
