[php-src] Issue #8098: GC optimization of closure use itself

Issue: https://github.com/php/php-src/issues/8098 Comment Author: damianwadley PHP will automatically GC cycles when they reach 10000. https://3v4l.org/r2F3l https://www.php.net/manual/en/features.gc.collecting-cycles.php > When the garbage collector is turned on, the cycle-finding algorithm as described above is > executed whenever the root buffer runs full. The root buffer has a fixed size of 10,000 possible > roots (although you can alter this by changing the GC_ROOT_BUFFER_MAX_ENTRIES constant in > Zend/zend_gc.c in the PHP source code, and re-compiling PHP). When the garbage collector is turned > off, the cycle-finding algorithm will never run. However, possible roots will always be recorded in > the root buffer, no matter whether the garbage collection mechanism has been activated with this > configuration setting. Please describe the bug you are trying to report.
