Building a debug tests of Higgs[¹] doesn't finish building and runs out of
memory with dmd-2016-10-10 (v2.073.0-master-9a935f6). Only takes about 2GB with
dmd-2016-10-09 (v2.073.0-master-321c95e).
According to verbose output it hangs at `semantic3 parser`.

Digger says it's caused by https://github.com/dlang/phobos/pull/4286.
