Can't get Objective-C class method to compile.

[Jeremie Pelletier via Digitalmars-d]

Hello, I'm trying out the new interface to Objective-C and I 
can't get this to compile:

    module main;
    extern (Objective-C) {
        interface NSObject {
            void release() @selector("release");
        }

        interface NSString : NSObject {
            const(char)* UTF8String() @selector("UTF8String");
        }

        interface NSProcessInfo : NSObject {
            static NSProcessInfo processInfo() 
@selector("processInfo");

            NSString operatingSystemVersionString()
                @selector("operatingSystemVersionString");
        }
    }


    void main() {
        import std.stdio;

        auto str = 
NSProcessInfo.processInfo.operatingSystemVersionString;
        writeln(str.UTF8String);
        str.release();
    }

I used the following command line:

dmd main.d -L-framework -LFoundation

I'm running the latest dmd (2.069.2) and it exits after printing 
this message:

Assertion failed: (ethis), function 
objc_callfunc_setupMethodCall, file objc_glue.c, line 276.
Abort trap: 6

This is from the class method call to NSProcessInfo.processInfo.

I've tried without the selector but get a linker error on 
__D4main13NSProcessInfo11processInfoYZC4main13NSProcessInfo.

I'm not sure if it is a bug or if I'm not using it correctly so 
I'm asking here before opening a bug report :)
