From 7ee41feba6b834d9e17e634bfbf222c4d8dd1a4f Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 23 May 2022 10:08:18 +0200 Subject: locale: Remove private union from struct __locale_data This avoids an alias violation later. This commit also fixes an incorrect double-checked locking idiom in _nl_init_era_entries.
