Your ImageMagick distribution is using the self-contained, embeddable, zero-configuration edition of ImageMagick. One fix is to build ImageMagick and not use the --enable-embeddable option on the configure script command line. In the mean-time we'll take a look at the internal ImageMagick memory allocator and check for thread race conditions.

Thank you for your response!

I have turned off --enable-embeddable option in config.
It works magically now!
