Not a reload bug. RTL state gets mangled by pop_function_context_from
called underneath mangle_decl_string. We may be able to work around this
problem like so, but I'm still not certain that we're not borking something.
This can only be truely fixed by not doing such gross push/pop state
changes within the c++ front end.
