Okay, so we now there is a randomly but frequently segfault if (tracing) JIT is enabled under FPM,
which happens at:
````
#0 0x000055bbf04c0f25 in ZEND_NEW_SPEC_CONST_UNUSED_HANDLER () at
/usr/src/debug/php-8.1.1/Zend/zend_vm_execute.h:10137
10137 ce = CACHED_PTR(opline->op2.num);
````
I'm afraid that is insufficient information to be actionable, and generally it's hard to
fix a bug which is not reproducible. :(
