--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Although with trunk it crashes the compiler:
l.cc: In member function 'void S::_foo(const ConverterFunction&, const
ConverterFunction&)':
l.cc:20:34: warning: unused parameter 'converterBack' [-Wunused-parameter]
20 | const ConverterFunction& converterBack)
| ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
l.cc: At global scope:
l.cc:29:1: error: Two symbols with same comdat_group are not linked by the
same_comdat_group list.
