ImageMagick from V6.5.7-2 to V6.5.7-5, in Centos 5.x 64bit OS, show message:

php: magick/semaphore.c:220: DestroySemaphoreInfo: Assertion `(*semaphore_info) != (SemaphoreInfo *) ((void *)0)' failed.
Aborted

why?

We need to reproduce the problem before we can offer a solution. Can you post a command line or script that we can use that will generate the exception? You could also post a stack trace. With the trace we should be able to track the source of the problem and fix it.

He might not be able to, but I'm seeing the same error on every machine. All you have to do is type
convert -list
and you get that error. Or I do. This is on RedHat Enterprise Linux 2.6 kernel.

Does the problem occur with the latest ImageMagick release, 6.5.7-10? We're running it under CentOS 5.4 and concert -list returns without complaint.

Yes, thanks! It works now on all our machines, including AIX, RHEL5, and SuSE SLES 9.
I notice the ImageMagick page says the latest release is 6.5.8, but the latest I actually saw on the mirrors was 6.5.7-10 as you said. Things move fast around here, I guess!

Recently, I had a similar error message when compiling a project with MagickCore and MagickWand. I had resolved this problem by compiling only with MagickWand. Hope this helps ...
