in module_desctructor_zval, the module name is pcre
 [2018-11-29 12:37 UTC] mate at sla dot hu
Is the pcre_globals->pcre_cache should be dumpable by print_ht?

opcache mem was full,
after increasing opcache.memory_consumption this does not happen

i suspect there is another error during runtime because of memlimit, which bailsout, and later during shutdown, the crash happens

Does this still happen to you with any of the actively supported
PHP versions[1]?
