segmentation fault in spl_perform_autoload about php-src HOT 6 CLOSED

The issue with these crashes is that they crash later than the point where it actually went wrong. This report isn't actionable without more details or a reproducer.

A couple of questions:

• Which extensions are you using?
• Does it reproduce without Opcache?
• Is it possible for you to run php-fpm under Valgrind or with ASAN compiled in?

from php-src.

extensions:

        php8.2-apcu \
        php8.2-cli \
        php8.2-curl \
        php8.2-mbstring \
        php8.2-opcache \
        php8.2-readline \
        php8.2-redis \
        php8.2-xml \
        php8.2-zip \
        php8.2-pgsql \
        php8.2-gd \
        php8.2-bcmath \
        php8.2-redis \

php was installed from the repository deb http://ppa.launchpad.net/ondrej/php/ubuntu focal main

I see you're using a third party extension, the problem can also be caused there.
Please also answer the other questions I asked earlier.
Without a reproducer or without a trace from Valgrind or ASAN we cannot find and fix the issue.
I see 4 people thumbed up this report, which indicates more people experience this, if they have any more information then that would be helpful.

Could you explain to me how to run ASAN into docker? Do you have a docker image with ASAN?

from php-src.

(Note that the "official" php Docker images are not maintained by us.)

You would need to compile PHP yourself in that case and configure it with the --enable-address-sanitizer option. However, given the question it's probably easier in your case to run Valgrind which won't need custom compilation.

In that case, you will need to install the valgrind package and also the debug symbol package for php-fpm probably.
Then to run it:

• set the environment variable USE_ZEND_ALLOC=0
• Run valgrind php-fpm -F to run fpm in foreground mode under Valgrind

Then try to trigger the bug and send us the output from Valgrind.
