Hi Jack,

the problem was that the failure only occurred when compiled without
asserts. So just removing the XFAIL does cause troubles on builds with
asserts enabled. I tightened the test case in r183025 such that it
should now behave as expected on asserts and non-asserts builds.

Thanks again for reporting and looking into this.

Cheers,
Tobias
