From 26fb83d00925234e9c5617b9ed4ebd693a1aae46 Mon Sep 17 00:00:00 2001 From: Dominic Hargreaves <d...@earth.li> Date: Thu, 6 Jun 2019 21:02:25 +0100 Subject: [PATCH] Fix pathological test failure case in ext/POSIX/t/mb.t This new test fails in an environment where LANG is set to one thing and LC_ALL is set to another, and where LANG is set to a locale which is not installed in the environment in question. Such a test environment is arguably broken, but appears in common chroot setups such as Debian's sbuild tool where LANG is inherited from the parent environment, and LC_ALL is used to override it.
