Php 8.3 SegFault

[Electro707]

Hello,

I am not familiar with php, so let me know if you need more information on my instance, or how to get a better traceback (php doesn't make that easy)

I am running scramble==v0.10.13 under php v8.3.10. When I access /docs/api in my Lychee instance, I get a segmentation fault.

Normally I would get a "Maximum call stack size" error, as per below

Dedoc\Scramble\Support\Type\TypeWalker::Dedoc\Scramble\Support\Type\{closure}:19 Maximum call stack size of 8339456 bytes (zend.max_allowed_stack_size - zend.reserved_stack_size) reached. Infinite recursion?
App\Http\Middleware\DisableCSP::handle:57 Maximum call stack size of 8339456 bytes (zend.max_allowed_stack_size - zend.reserved_stack_size) reached. Infinite recursion?; caused by

When I disabled zend.max_allowed_stack_size, the root cause is a segfault. I get the following backtrace after the child segfaults

hread 2.1 "php-fpm8.3" received signal SIGSEGV, Segmentation fault.
