If you overload an operator and use tyepof(this) as the type of the parameter, the compiler will throw an error about incompatible types. See the attached d source file for an example.

This can be worked around by using the struct/class name instead of typeof(this) for the parameter. If you're defining the operator in a template mixin (the case where I originally noticed the bug), you will need to pass the type as a template argument.

I am using gdc 2.051 compiled against gcc version 4.5.2 on an x64 Linux system
running Debian Squeeze. I initially posted this on gdc's bug tracker
(https://bitbucket.org/goshawk/gdc/issue/150/overloading-an-operator-breaks-when-using#comment-362929)
but they said it's likely a problem with the frontend.

Created an attachment (id=900)
Test source file that displays the errant behavior.

Reduced test case:


struct Foo {
    void opBinary(string op)(typeof(this) other) {}
}
void main() {
    Foo() + Foo();
}

It seems a dupe of my bug 4413
