--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Confirmed. Here's the relevant code:
template<int> struct B
{
void F2(int, int, int = 0);
};
template<int N> void B<N>::F2(int = 0, int, int) {}
57014.C:6:22: error: redeclaration of ‘void B<<anonymous> >::F2(int, int, int)’
may not have default arguments [-fpermissive]
6 | template<int N> void B<N>::F2(int = 0, int, int) {}
| ^~~~
57014.C:6:40: error: default argument missing for parameter 2 of ‘void
B<<anonymous> >::F2(int, int, int)’
6 | template<int N> void B<N>::F2(int = 0, int, int) {}
| ^~~
57014.C:6:31: note: ...following parameter 1 which has a default argument
6 | template<int N> void B<N>::F2(int = 0, int, int) {}
| ^~~~~~~
It would be nice if later declarations that name a template parameter could be
used to "fill in" any unnamed template parameters from the original
declaration, so that pretty printing isn't so ugly.
