[mod_cluster-dev] Problem with mod_proxy_cluster builded with Apache HTTPD 2.4.53 and higher

Hi I have a problem with mod_proxy_cluster builded with apache httpd 2.4.53 and actual 2.4.54 I got a segmentation fault errors when I used mod_proxy_cluster with these versions of Apache HTTPD When I tried to use apache's modul mod_proxy_balancer it is OK in previous version of apache httpd (2.4.52 and below) builded in some way, there were no similar errors. I'm building and running it on RHEL 7.7 Builded with: APR=apr-1.7.0.tar.gz APR_UTIL=apr-util-1.6.1.tar.gz HTTPD=httpd-2.4.54.tar.gz MOD_CLUSTER=mod_proxy_cluster-main.zip MOD_SECURITY=modsecurity-2.9.5.tar.gz NGHTTP2=nghttp2-1.47.0.tar.gz OPENSSL=openssl-1.1.1p.tar.gz PCRE=pcre-8.45.tar.gz Unfortunately I'm not able to do some core dumps due a restriction in my env. Is there anyone else who have similar problem? Or someone who can simulate and take a core dumps for deeper analysis? Thanks Jan
