Description: ------------ We try to run a Symfony based project and have some controllers with PHP8 annotations. But it crashes with a segmentation fault. (gdb) run bin/console ca:c Starting program: /usr/local/bin/php bin/console ca:c [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". // Clearing the cache for the prod environment with debug false Program received signal SIGSEGV, Segmentation fault. 0x00005555559a120b in zend_observer_fcall_end () (gdb) bt #0 0x00005555559a120b in zend_observer_fcall_end () #1 0x0000555555974eca in execute_ex () #2 0x00005555559076ba in zend_call_function () #3 0x0000555555907af5 in zend_call_known_function () #4 0x00005555557d0010 in ??

So maybe it's the yield at that point. PatchesPull RequestsHistoryAllCommentsChangesGit/SVN commits
