From 32182d7a7a67d0d204cd0a37bd211bfd0177bc27 Mon Sep 17 00:00:00 2001
Message-ID: <32182d7a7a67d0d204cd0a37bd211bfd0177bc27.1700093066.git.vivien@planete-kraus.eu>

Subject: [PATCH] stemmer: Resolve potential issue where stemmer may never be
initialized
If the initial locale was equal to the current stemming language, we may
never have initialized the stemmer (which could lead to crashes or
stemming being disabled).
So we force the reload to always happen on initialization.
CC: #558
