I am still having this visiblity issue: 

This is with clang from svn updated yesterday.

The only workaround I have been able to find is to not use 
-fvisibility=hidden for libraries which export template instantations 
— this workaround causes some linker warnings related to different 
visiblity of internal stdlib symbols which I think are wrong, becaue 
even if I ensure all headers are included with same visibility¹ the 
warnings persist, but given how I can’t use the visibility pragma to 
export the explicit templates, I have a feeling that this pragma isn’t 
100% effective…

¹ Using #pragma GCC visibility push(…) / pop.
