Obviously the input is malformed, but probably still should not ICE.

Subject: Bug 41774

Author: jakub
Date: Mon Nov  2 13:39:46 2009
New Revision: 153805

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=153805
Log:
        PR c++/41774
        * c-pragma.c (visstack): Change into vector of ints rather than
        enum symbol_visibility.
        (push_visibility): Add kind argument, push default_visibility together
        with kind.
        (pop_visibility): Add kind argument, return true if successful, fail
        if visibility stack is empty or if stack top is of different kind.
        (handle_pragma_visibility): Don't check length of visstack, instead
        call pop_visibility and issue diagnostics if it failed.  Pass 0
        as last argument to push_visibility and pop_visibility.
        * c-pragma.h (push_visibility): Add kind argument.
        (pop_visibility): Likewise.  Return bool instead of void.

        * name-lookup.c (handle_namespace_attrs): Pass 1 as last argument to
        push_visibility.
        * parser.c (cp_parser_namespace_definition): Pass 1 as argument to
        pop_visibility.
        * rtti.c (push_abi_namespace): Pass 2 as last argument to
        push_visibility.
        (pop_abi_namespace): Pass 2 as argument to pop_visibility.

        * g++.dg/ext/visibility/namespace3.C: New test.
