Re: Apache segmentation fault when loading libphp7.so

You could try logging PHP startup errors: https://www.php.net/manual/en/errorfunc.configuration.php#ini.display-startup-errors

this did not work. I have nothing on my screen or in any log. php -i sais I used the correct php.ini

Or try running Apache daemon using valgrind: https://www.valgrind.org/docs/manual/quick-start.html

This was REALLY strange. I don't know if this is expected behaviour, but using valgrind, the server is up and running. I created a full output, ... (valgrind --leak-check=full --show-leak-kinds=all -v /usr/local/httpd-test/bin/httpd -k start) ... which you can find here: https://pastebin.com/Dwgjxjgj Greets Kai

Hello Keith, no, it's not mod_alias, because debug log sais the module is loaded. Without mod_alias it looks like below. When I comment out phplib7.so, the server starts and is online. I don't know if it helps: httpd sends a return code 139. PHP in the CLI works.

Hi Kai, Is it seg faulting when the mod_alias mod is loaded? Can you try to run apache and PHP module without the mod_alias module to see if it happens then? Kind Regards, Keith Roberts On 11/08/2020 11:21, Kai Fürstenberg wrote:
