Summary: Attributes on member classes of class templates and member class templates of class templates are not currently instantiated. This was discovered by Richard Smith here: http://lists.llvm.org/pipermail/cfe-dev/2018-September/059291.html This commit makes sure that attributes are instantiated properly. This commit does not fix the broken behavior for member partial and explicit specializations of class templates.
