I followed the instructions to install Phabricator with Nginx and PHP-FPM. I can view most pages on the site. However, navigating to /config/issue/ or /config/cache/ returns a 502 error and produces a core dump from PHP-FPM. Refreshing occasionally loads the cache page successfully, but I haven't been able to get to the issue page at all.
This is the output from coredumpctl info, the full dump is attached.
