Subject: error.c (dump_type_real): Handle NAMESPACE_DECL.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=009425e185c045c143997bbb3030644b834475a2;p=gcc.git

error.c (dump_type_real): Handle NAMESPACE_DECL.

	* error.c (dump_type_real): Handle NAMESPACE_DECL.
	* parse.y (base_class.1): Avoid crash on error.
	* decl.c (make_typename_type): If context is a namespace, the code
	is in error.
