APC 3.0.17 - regression?

Hi, I saw the security notice and updated 3.0.17 release today, so I decided to upgrade my installation. Now Wordpress (the only PHP application I have installed to test) works correctly on the first page load, but the second (presumably cached) load cuts the HTML document half way. This is in Apache's error log: zend_mm_heap corrupted zend_mm_heap corrupted [Wed Mar 26 15:47:22 2008] [notice] child pid 386 exit signal Segmentation fault (11) If I go back to 3.0.16 I have no problems. The precise server setup is: Ubuntu 7.10 AMD64 Apache 2.2.4-3ubuntu0.1 PHP 5.2.3-1ubuntu6.3 /etc/php5/conf.d/apc.ini: extension=apc.so apc.enabled=1 apc.shm_segments=1 apc.shm_size=128 apc.ttl=7200 apc.user_ttl=7200 apc.num_files_hint=1024 apc.mmap_file_mask=/var/cache/apc/apc.XXXXXX apc.enable_cli=0 Is this a regression or would you suspect something else in my installation is at fault? 3.0.16 has worked flawlessly for many months.
