--- Comment #5 from Richard Smith <richard-llvm at metafoo.co.uk> ---
> As far as I can tell, the COMDAT definitions in a.cpp and main.cpp are identical. The problem doesn't seem to be that a COMDAT is missing symbols.

This didn't turn out to be entirely true: because the _ZTH function is an alias
to __cxx_global_var_init, and __cxx_global_var_init is in the COMDAT, the _ZTH
symbol effectively points into the COMDAT too.

In any case, the conclusion is the same: __cxx_global_var_init shouldn't be in
the COMDAT. Fixed in cd4d6d7.
