Hi.Attached an small patch which Opus thinks that's fix an Memory leak, this was found by build and testing for cloudauth filter.
Best Regards Aleks
From 274eb9255bedb5c1b44035917e8be39c0467ed4e Mon Sep 17 00:00:00 2001 From: Aleksandar Lazic <[email protected]> Date: Sat, 17 Oct 2026 21:40:58 +0200 Subject: [PATCH] BUG/MINOR: filters: free the error message of the filter-config parsers flt_precheck_instance() passes a message to the ->parse() callback of the filter classes, which may allocate it with memprintf() to report an error. The message was reported with ha_alert() but never released, so it leaked each time a "filter-config" instance failed to be parsed, for instance with "filter-config trace id t1 bogus-option", as reported by ASAN. This only happens on configuration errors, which are fatal at boot, but the instances of the proxies created at runtime are parsed the same way. Let's release the message once reported, and also on success in case a parser fills it without failing. This was brought by commit b3075cf7f ("MEDIUM: filters: Parse and finalize filter-config instances") in 3.5-dev9, so no backport is needed.
