Regressions in clang-6 need to be resolved

There are two FreeBSD ports that fail to compile with clang-6 with errors that don't look like genuine C++ errors.

Here are the bug reports with attached testcases:

https://bugs.llvm.org/show_bug.cgi?id=36915

https://bugs.llvm.org/show_bug.cgi?id=36916

I suspect these are regressions.

Is it possible to get an estimated time when these will be fixed?

I've marked them as 6.0.1 blocker to get the bugs some more visibility.
