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