Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |DUPLICATE Status|UNCONFIRMED |RESOLVED --- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Yes it is a dup. The following should also be rejected but currently is not: ``` template<class T, class T1 = int*(T[5])> int f(T*); int j=f<void>(nullptr); ``` Basically function arguments (including concepts "arguments") decay too early for arrays to pointers. *** This bug has been marked as a duplicate of bug 24664 ***
