--- Comment #13 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
This is another bug related to incremental linking and LTO. I will redirect
them all to PR67548. The testcase now works on mainline GCC in a sense that the
duplicate is gone and we get missing typeinfo:
lib1.lib:<artificial>:typeinfo for CDialogBase: error: undefined reference to
'vtable for __cxxabiv1::__class_type_info'
/usr/bin/ld: the vtable symbol may be undefined because the class is missing
its key function
collect2: error: ld returned 1 exit status
that seems intended.
