From: Nick Wilson <163766-ncw@users.noreply.gitlab.gnome.org> Date: Mon, 27 Oct 2025 16:42:45 +0100 Subject: glib/tests/regex: Add a future-proof test case for missing back reference This test applies to both old and newer versions of PCRE2 where back reference error has now increased the granularity and is referred as PCRE2_ERROR_MISSING_NUMBER_TERMINATOR instead.
