Another one: some extensioms suffer from the fact that the macro GC_G
was removed from
https://github.com/php/php-src/blob/master/Zend/zend_gc.h
Some of the removed functionality has been reintroduced in gc_status
https://github.com/php/php-src/commits/master/Zend/zend_gc.h

Examples using GC_G: v8js, xdebug, tideways.
v8js was using gc_active to check if garbage collection was running.
I did a wild guess to fix it:
https://github.com/Jan-E/v8js/commit/997df065d3cd06a9b11e399458c391eb797a850e#diff-dc446a69201ccda44a33d111152f6c8c

Are the changes to zend_gc.h documneted?
