--- Comment #1 from Kai Tietz <ktietz at gcc dot gnu.org> ---
This issue is a known binutils' ld bug. Issue here is that object-file
arguments aren't treated proper for LTO-plugin.
Work-a-round for this is adding all files into library by ar-tool, and doing
linking via it (Side-note be aware that you will need to mark classes then via
dllexport).
