--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Confirmed, started with r7-6608-ga56c0ac08242269b. We rejected the code before
the revision:
pr91759.cc:8:1: error: deduction guide ‘N::X(int)-> N::X<int>’ must be declared
in the same scope as ‘N::X<T>’
X(int) -> X<int>;
^
pr91759.cc:3:12: note: declared here
struct X{ X(int); };
^
