minimal example

In the attached example, linking fails with clang trunk with the -g switch:

/tmp/t-1d6fe7.o:(.debug_info+0x66): undefined reference to
`_u::_t<void>::_literal'
clang: error: linker command failed with exit code 1 (use -v to see invocation)

The symbol is actually defined on line 51.
