I'm not sure if the following is relevant, but I found it in cp/mangle.c: /* Since we now use strcmp to compare typeinfos on all targets because of the RTLD_LOCAL problem, we need to munge the typeinfo name used for local classes of static functions to fix g++.dg/abi/local1.C. We do that by pretending that the function is in an anonymous namespace. */ static bool needs_fake_anon (const_tree decl) Jery
