Hello,
if i include <boost/static_string.hpp> i get errors in std::variant:

/usr/include/c++/12/variant:774:72: Fehler: Templateargument 4 ist ungültig
  774 |                       void_t<decltype(_Arr<_Ti>{{std::declval<_Tp>()}})>>
      |                                                                        ^~
/usr/include/c++/12/variant:804:76: Fehler: Templateargument 3 ist ungültig
  804 |     struct __accepted_index<_Tp, _Variant, void_t<_FUN_type<_Tp, _Variant>>>
      |                                                                            ^

Can you retrace that?
boost 1.79
gcc 12.1 -std=gnu++2b
openSuse Tumbleweed

thx
