Occurred rarely (about 12-20 times a day on a site that has about 200,000 page views a day). Narrowed the problem down to calls to virtual(). I had 3 to 4 per page. Changing virtual() out with include() or require() completely removed segfaults. Apache 2.2.17 PHP 5.3.5 from FreeBSD ports (did not occur when using PHP 5.2.17 from source).
