ImageMagick-6.5.7.2nb1
>Description:
Most ImageMagick command line tools (eg mogrify and convert)
dump core on exit due to an assertion error.

This breaks eg. pkgsrc/multimedia/dvdrip.

Imho this needs to be fixed before the pkgsrc Q4/09 release.
>How-To-Repeat:
$ mogrify
Version: ImageMagick 6.5.7-2 2010-01-08 Q16 http://www.imagemagick.org
[...]
assertion "(*semaphore_info) != (SemaphoreInfo *) NULL" failed: file 
"magick/semaphore.c", line 220, function "DestroySemaphoreInfo"
Abort trap (core dumped)

>Fix:
The problem is mentioned in the ImageMagick mailing list.
ImageMagick 6.5.7-9 seems to fix it, but more checks
are needed whether other bugs are introduced instead.
