I have a test case and a patch that fixes this. I found the problem on
mingw32 but I believe that this will be a problem on every platform, and for
every version of gcc (gnu Objc runtime only).
I will attempt to attach the testcase and patch.

test case #2a
Requires the protocolCase2b.m attachment as well.
Compile using gcc -g protocolCase2b.m protocolCase2.m -lobjc -o protocolCase2
run the program and watch it crash.
Don't change the link order, 2b.m must occur before 2.m or it won't fail.

This is a dup of bug 18255. The bug is really in the front-end which should mark the supper protocol
as be staticly initialized.
*** This bug has been marked as a duplicate of 18255 ***

No no, it is not a duplicate. You will see that test case #1 will still fail
even after you fix bug 18255. libobjc fails to initialize statics if the
first static was initialized as a side effect of being used in a class.
