With DMD v2.099.0: ``` extern(C) bool foo1(int i) { return i != 0; } extern(C) char foo2(int i) { return i != 0; } alias F1 = extern(C) bool function(int); alias F2 = extern(C) char function(int); void main() { { // normal F1 f1 = &foo1; F2 f2 = &foo2; } { // explicit cast F2 f1 = cast(F2) &foo1; F1 f2 = cast(F1) &foo2; } { // cast, but mismatch F1 f1 = cast(F2) &foo1; // bug: no error - cast seems omitted F2 f2 = cast(F1) &foo2; // ditto } } ```
