Bug 14776 – shared library test - loadDR - segfaults on FreeBSD 10 when not building with -release

As discussed in issue# 14773, the druntime unit tests unfortunately are only built and run with -release. However, if you build them without -release and run them on FreeBSD 10, then you get this failure: Testing link Testing load Testing linkD Testing linkDR Testing loadDR Makefile:28: recipe for target 'obj/freebsd/64/loadDR.done' failed gmake[1]: *** [obj/freebsd/64/loadDR.done] Segmentation fault gmake[1]: Leaving directory '/usr/home/jmdavis/Programming/github/druntime/test/shared' posix.mak:206: recipe for target 'test/shared/.run' failed gmake: *** [test/shared/.run] Error 2 I don't know for sure that this is FreeBSD-10 specific, since I haven't run the druntime unit tests without -release on anything else, but I expect that it's related to issue# 14663, which definitely is specific to newer versions of FreeBSD, which is why I'm marking this as FreeBSD-only. I suppose that I could just put it under issue# 14663 (and perhaps I should), but I don't know that they're the same bug, so I figured that I'd list this one separately just in case.
