It says uninstalled since I installed it and then got the error. So I uninstalled it and compiled the master branch and that fixes the issue.

Running test php file gets a segfault:
root@server:/var/www/html# php -f test.php
PHP Fatal error: Uncaught GearmanException: Failed to set exception option in /var/www/html/test.php:3

Segmentation fault (core dumped)

It appears the issue is fixed in the latest version of the gearman extension (https://github.com/php/pecl-networking-gearman). Unfortunately this was fixed after the 2.0.6 release.

This appears to be fixed in Ubuntu 20.10 (Groovy Gorilla): php-gearman_2.0.6+1.1.2-8

[Jeremy Norris (jeremy.norris)]

Is this going to be fixed in 20.04? The php-gearman package as currently distributed in 20.04 is utterly broken and doesn't work at all (it continually segfaults).

This appears to be due to: https://github.com/wcgallego/pecl-gearman/issues/73
