Description

When trying to upload files using Apache and Firefox (Chrome, etc). The file tries to upload, takes a several minutes even for a 5mb upload and then produces the error.

I have tested this on my main server but also a freshly installed server with the exact same errors. The version of this project that uses Docker seems to work.

Resulted in this output:
'''

Error 503 "Service Unavailable

The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later."

This needs more info like some piece of code triggers the segfault or at least install debug symbol so there is more info in core dump.

Hey, Castopod's core maintainer here 👋

Just wanted to say that Castopod was not made compatible with php8.2 yet, so errors are expected if used with v8.2. I think this should be closed.

@yassinedoghri Thank you for your input. Optimally, no PHP code should be able to cause segfaults / crash the process (with some exceptions, like stack overflows until recently, high memory consumption with a memory_limit config that's too generous, FFI, etc).

@sysadminpower2019 Thank you for adding the backtrace! Unfortunately it's still not very helpful, the backtrace is probably in an unrelated place. Is there anything special in your configuration? E.g. do you have JIT enabled? That's a common cause for crashes. Do you have opcache enabled?

If you can, compiling PHP yourself and enabling the ./configure --enable-address-sanitizer flag could be helpful. In that case, you should also run PHP with the USE_ZEND_ALLOC=0 environment variable set.
