   This may be fixed via ef5844a

   I wasn't able to reproduce the reported assertion, but got a crash instead.
   The commit above fixed the crash. Assertion is not reproducible.

   @dstogov Thanks! Seems okay, but still getting some segfaults on tests/AnnotationTest.php and several others (currently testing on arm64).

   Reproduce by cloning and running php .github/nightly.php with the following ini:

   memory_limit = -1
   zend.assertions = 1
   display_errors = On
   display_startup_errors = On
   
   [opcache]
   zend_extension=opcache.so
   
   opcache.memory_consumption=4096M
   opcache.enable=1
   opcache.enable_cli=1
   opcache.jit=tracing
   opcache.validate_timestamps=0
   opcache.jit_buffer_size=128M
   opcache.file_update_protection=0
   opcache.max_accelerated_files=1000000
   opcache.interned_strings_buffer=64
   
   opcache.jit_prof_threshold=0.000000001
   opcache.jit_max_root_traces=  100000
   opcache.jit_max_side_traces=  100000
   opcache.jit_max_exit_counters=100000
   opcache.jit_hot_loop=1
   opcache.jit_hot_func=1
   opcache.jit_hot_return=1
   opcache.jit_hot_side_exit=1
   
   opcache.jit_blacklist_root_trace=255
   opcache.jit_blacklist_side_trace=255
   
   opcache.protect_memory=1

   @dstogov Sorry, I meant to link the repo https://github.com/danog/php-src for the reproducer :)

   I don't have ARM and I can't reproduce this on x86_64 running php --repeat 2 vendor/bin/phpunit tests/AnnotationTest.php. Running this under QEMU would take hours. I need a reduced teat case.

   @dstogov Okay, will try whipping up something once I have some time!

   In the meantime, could you also take a look at the some JIT-related issues I recently created?

   This one is fixed. Please open a new issue for AnnotationTest.php (reproducible jit_bugs scenario would help).
