Comment 2 Martin Matuska freebsd_committer freebsd_triage 2016-07-17 20:37:31 UTC 
Using e.g. de_DE.UTF-8 as locale has the same effect
Comment 3 Martin Matuska freebsd_committer freebsd_triage 2016-07-18 08:11:44 UTC 
I have narrowed this down to a endless loop in wcscoll_l():
for (pass = 0; pass <= table->info->directive_count; pass++) { }

I can confirm this is fixed by John Marino's patch in DragonflyBSD:
