Please install the debug symbols or compile PHP in debug mode.

Which c-client do you use? If it is an old version (<2007) please try using 2007e.

Hi PHP,
We are having exactly the same issue with Sugarcrm 4.51 email module which uses PHP Imap function to pull emails.

Fedora 9
Apache/2.2.9 (Fedora) 
PHP 5.2.9


Apache throws a segmentation fault 11 error when IMAP tries to pull an email with long to or CC email address list.

Please re-open this BUG.
