Bug 5532 – Overloading an operator breaks when using typeof(this)

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 attachment 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
