I don't have a system with the failure so I was working blind. Here is a rework of the patch. Bob >From 76dafb0dde4f8d685eb2b4b43fbf3c1cf9f0ff4b Mon Sep 17 00:00:00 2001 From: Bob Proulx <bob@proulx.com> Date: Thu, 26 Jul 2007 02:19:49 -0600 Subject: [PATCH] sort: Improve sort --random-sort test. * tests/misc/sort-rand: If "locale" is available pick a random non-C locale and check "sort --random-sort" behavior using it.
