HTTP 500 after deleting s9e cache file on PHP 7.0

Purging the cache in phpBB 3.2.0 on PHP 7.0 causes HTTP 500 error which is gone after several page reloads.

The error text looks like:
[Mon May 15 07:22:21.560948 2017] [cgi:error] [pid 10637] [client *.*.*.*:50802] End of script output before headers: php, referer: https://domain.com/

Random deleting cache files gave the result that HTTP 500 error raises after deleting the s9e_renderer cache file, like s9e_renderer_b6be1796cd7dd1aa72151bc47f370952ae9a5e87.php.

Setting the php.ini directive pcre.jit to 0 solves the issue. Also, setting the $configurator->rendering->engine->enableQuickRenderer = true; to false in /phpbb/textformatter/s9e/factory.php solves the issue as well.
