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