APC 3.0.8 and PHP 5.0.5 mystical behavour

Hi, I ran into some problem using PHP 5.0.4 / APC 3.0.8. I get an error randomly from HTML_QuickForm (3.2.5): Fatal error: Call to undefined method HTML_QuickForm_group::HTML_QuickForm_element() in /usr/lib/php/HTML/QuickForm/group.php on line 97 HTML_QuickForm_group extends HTML_QuickForm_element, so in this line the parent constructor is called but not found. This must be an APC problem cuz it does not happen without APC. Even not with eaccelerator. APC (installed with 'pecl install APC') config follows: apc APC Support enabled Version 3.0.8 MMAP Support Disabled Revision $Revision: 3.68 $ Build Date Aug 25 2005 10:06:32 Directive Local Value Master Value apc.cache_by_default On On apc.enable_cli Off Off apc.enabled On On apc.file_update_protection 2 2 apc.filters no value no value apc.gc_ttl 3600 3600 apc.max_file_size 1M 1M apc.num_files_hint 2000 2000 apc.optimization Off Off apc.shm_segments 1 1 apc.shm_size 32 32 apc.slam_defense Off Off apc.ttl 7200 7200 apc.user_entries_hint 100 100 apc.user_ttl 7200 7200 Shall I drop a bug report for this?
