"#8  0x00000000009611b0 in php_execute_script () at"

There is a script that is starting to be executed. It might be in the new preloading, or it could be in the older `auto_prepend_file` functionality, but it does appear to be some PHP script being run.

Without more info about what is being run, or at least the conditions that the error occurs under, it's unlikely anyone would be able to figure out what is causing it.

I want upgrade the version from php5.4 to php7.3.24. I just refresh the website page of our service by using php7.3.24. But return 502 on the page. And one of the php-fpm work process exit with segment fault.

Is this still an issue with any of the actively supported PHP
versions[1]?  If so, could you please provide a script to be able
to reproduce this problem?
