I checked the multilib issue, and couldn't see it. Had a look on D's bugtracker, and found this related issue: https://issues.dlang.org/show_bug.cgi?id=18519 Raised a pull request against upstream phobos that fixes the test itself: https://github.com/dlang/phobos/pull/6824 Though I haven't yet checked running in dejagnu that the desirable behaviour transfers over well.
