NULL value for web/secure/base_url generates a SEGSERV error

[hd-jeroen]

Preconditions (*)

1. Magento 2.4.2
2. PHP 7.3 or PHP 7.4 through FPM
3. MySQL 8.0

Steps to reproduce (*)

1. Set the value for web/secure/base_url in core_config_data table to NULL
2. Flush all Magento caches
3. Refresh the website

Expected result (*)

1. An exception being thrown telling the store URL is invalid

Actual result (*)

1. PHP-FPM runs into an error and throws a SEGSERV exception

[25-Mar-2021 13:46:59] NOTICE: [pool www] child 2842 started
[25-Mar-2021 13:47:07] WARNING: [pool www] child 2839 exited on signal 11 (SIGSEGV) after 13.986447 seconds from start

Additional info

In our case, due to a human error the database field for web/secure/base_url got set to NULL. I agree that this shouldn't usually happen, but it did.

I spent ages looking into the issue, since Magento CLI as well as the webpage, started throwing SIGSERV errors, meaning that PHP was trying to access an invalid memory pointer. This has been traced back to the erroneous configuration setting.

Hi @dehaan-jeroen,
From the first look, it seems like you're just not providing one of the mandatory configuration options, which is OK to be failing.
Could you provide additional info? What is the use case of not defining the base URL?
