semaphore issue

[jbnance]

Dear gurus,
Over the weekend we upgraded our RHEL 5 servers which are running PHP 5.2.17 (with the PHP extensions MagickWand and iMagick - which were also "upgraded" at the same time since they were rebuilt for the new version of ImageMagick) to ImageMagick 6.7.7-3 (from 6.6.3-0). We immediately started seeing these messages in our Apache/PHP error logs:

[Sun Jun 17 03:21:49 2012] [notice] child pid 10719 exit signal Aborted (6)
httpd: magick/semaphore.c:290: LockSemaphoreInfo: Assertion `semaphore_info != (SemaphoreInfo *) ((void *)0)' failed.

Any thoughts on this issue?

I believe I've found a solution to the issue, but I don't know what was causing it. At compile time I was including "--enable-zero-configuration" as an option. Rebuilding without that seems to have fixed the issue.
