Probably similar.

We don't merge correctly two or more types with visibility attributes
in template argument lists. This was not causing problems before, but
does as we start to mark more symbols hidden.

The attached patch fixes that too. The apple linker is happy at least
with the delta reduced testcase I had. I will leave a new build
running during the night.
