It is more likely that users do not notice it. I have Piwik running with
PHP 5.3 and php_opcache.dll (Centos 5) and it segfaults:

[Sun Sep 01 17:06:53.131410 2013] [core:notice] [pid 25411] AH00052:
child pid 25451 exit signal Segmentation fault (11)
[Sun Sep 01 17:08:18.561917 2013] [core:notice] [pid 25411] AH00052:
child pid 25453 exit signal Segmentation fault (11)

However, nothing special is displaying on the page. You have to grep
your Apache error_log to know that it happens. How did you notice?
