484	CRITICAL: Apache crashes when using MapCache regex dimensions (PCRE2 access violation)	dpelissiry	Jeff McKenna	When using MapCache regex dimensions on MS4W, both Apache (httpd.exe) and mapcache_seed consistently crash with an access violation in pcre2-8.dll. This reproduces on both a fresh MS4W install and an existing setup, and only occurs when regex dimensions are used. After digging into the MapCache source, it appears the PCRE2 code path for regex dimensions may be using uninitialized values when calling pcre2_compile and pcre2_match, which could explain the crashes. I was also wondering if there is an MS4W build available that uses the legacy PCRE instead of PCRE2, as a possible workaround.	defect	closed	critical	5.2.0 release	MS4W - MapCache	5.0.0	fixed		TC Haddad dpelissiry@…
