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.
