frankly this still exists with 7.1.3RC1 and no feedback at all after trying to provide the requested
informations is not cool

any news here?
memleaks are really serious because you need to configure the server be it httpd or fpm to more
often restart forkers and that has a performance impact up to not even get the machine to 100% CPU
because it's busy with fork processes

i optimized the environment to use "httpd -X" (no forking) and ignore the loop-settings
for code-coverage in case 'valgrind' is part of the game - finally that leads to easily
profile every php-build with one call for each page of a sample cms-setup and report memleaks with
minimized output
