The constant name is usually interend. Without opcache, compilation always interns strings. Without opcache, compilation does not intern (new) strings, but persisting of script does. If a script is not stored in shm the constant name will not be interned. The building of enum backing stores was missing a addref for the constant name, leading to a double-free when releasing constants and backing stores of enums. Fixes GH-12366 Closes GH-12405
