dl() breaks expectations regarding permanent or interned strings #9196
Description
Description
Creating this ticket to keep track of some issues related to dl() and permanent / interned strings:
Extensions loaded during a dl() call will try to allocate persistent interned strings for class names, function names, ini entries, etc. Normally, this is not allowed during a request.
The default in-request implementation of zend_string_init_interned still allows it, but the opcache implementation will simply return a non-interned string.
Calling dl() breaks in RC_DEBUG builds: #8606
This also breaks internal enums. The test in this branch will crash in debug builds: https://github.com/php/php-src/compare/master...arnaud-lb:php-src:internal-enums-dl-crash?expand=1
