Simen Kjaeraas <simen.kja...@gmail.com> changed: What |Removed |Added ---------------------------------------------------------------------------- Keywords| |ice CC| |simen.kja...@gmail.com --- Comment #1 from Simen Kjaeraas <simen.kja...@gmail.com> --- Further simplified: template Mixin() { void fun(const int) { } } class Foo { mixin Mixin!(); mixin Mixin!(); } class Bar : Foo { override void fun(int) { } // Line 11 } This gives a slightly different stack trace (top calls are still the same). This difference is caused by templatization of Foo, and can be disregarded. Changing the type on line 14 from A to const(A) removes the crash. Rewriting to using a single invocation of Mixin with two function definitions inside gives this message: Error: function void foo.Bar.fun(A) does not override any function, did you mean to override void foo.Foo!int.Foo.Mixin!(A, B).fun(const(A))? --
