From 3150a4542f81f0f953e68170bda462b0a501ff29 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sl=C3=A1vek=20Banko?= Date: Sun, 8 Sep 2024 12:20:25 +0200 Subject: kjs - pcre: Fix crash if regexp is invalid. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the regular expression is invalid and pcre2_compile ends with error, match_data will remain uninitialized, which in turn leads to crash on pcre2_match_data_free in RegExp destructor.
