Failed. Elastic PHP agent extension is not enabled

Set up the Agent manually as explained in:
https://github.com/elastic/apm-agent-php/blob/main/docs/setup.asciidoc
Enable the extension by adding the following to your php.ini file:
extension=/opt/elastic/apm-agent-php/extensions/elastic_apm_loader.so
elastic_apm.bootstrap_php_part_file=/opt/elastic/apm-agent-php/src/bootstrap_php_part.php

And after this php -m gives "Segmentation fault".

The .ini files are created, if I edit /etc/php/8.1/cli/conf.d/98-elastic-apm.ini, and place elastic_apm.bootstrap_php_part_file in a comment (leaving extension= enabled), php -m will give correct output; listing the apm extension. But actual php scripts won't work.

Seems to be fixed by a dist-upgrade
