Bug 13127 – Cannot deduce function with int[][] argument and "in" parameter

This code works in DMD 2.065.0 but not in 2.066.0-b3: void foo (T)(in T[] src, T[] dest); void main () { int[][] a; foo(a, a); } The error message is: main.d(14): Error: template main.foo cannot deduce function from argument types !()(int[][], int[][]), candidates are: main.d(9): main.foo(T)(in T[] src, T[] dest) If I remove "in" or if "a" is of type "int[]" it compiles.
