Bug 13694 – Typesafe variadic function template overload fails to match to any template

Below minimal code used to work with DMD 2.064.2 amd64 fails with DMD 2.066.1 amd64 struct S{} void foo(T)( string A, long E, T[] G ... ) {} void foo(T)( string A, T[] G ... ) {} int main() { S v; foo("A", v); // <- OK foo("A", 0, v); // <- used to be OK but now fails foo!(S)("A", 0, v); // <- workaround solution return 0; } $ dmd main.d main.d(13): Error: template main.foo cannot deduce function from argument types !()(string, int, S), candidates are: main.d(3): main.foo(T)(string A, long E, T[] G...) main.d(6): main.foo(T)(string A, T[] G...)
