From 4efa200f1ec1226b75bc80990e6a0514cd3762c9 Mon Sep 17 00:00:00 2001 From: Aquila Macedo Date: Fri, 7 Nov 2025 21:09:05 -0300 Subject: [PATCH] [PATCH] MDEV-38046 Make func_regexp_pcre tolerant to PCRE2 offset change PCRE2 10.47 reports the invalid escape in 'A\q' at offset 3 instead of 2. Update the expected result and add a --replace_regex in the test so the suite passes with both older and newer PCRE2 versions.
