It seems that test is wrong and new code is correct. On z/System the
situation is the following: function uses the incoming stack frame to
save any callee-saved registers. It's a responsibility of the caller
to create such stack frame. The test in question contains calls, and
it seems that these calls might overwrite the register save area (with
the old code). So, please fix the test :)
