seems you load zend_opcache twice?

"PHP Warning:  Module 'Zend OPcache' already loaded in Unknown on line 0"
"PHP Warning:  Zend OPcache: module registration failed! in Unknown on line 0"

could you please make sure you only load it once, then test it again?

Even if loaded two times it should not crash.

Underlying issue is that in zend_register_extension() we're not checking whether the Zend Extension was already loaded. Therefore the Zend Extension part is initialized and being shut down two times, second shutdown crashes.

The error message comes from the PHP module part being loaded by the Zend Extension. A Zend Extension without PHP module part would create no error but undefined behavior only.
