The issue was seen only on sparc platform and was occurring due to the alignment fault.

This looks very much like a duplicate of:

http://bugs.ghostscript.com/show_bug.cgi?id=691989

If it isn't, you need to report it in a way that doesn't rely on using "convert" or other third party package. Normally, you should report it to the package supplying the exe you actually call, and the developers of that should work out whether the problem is with their way of driving Ghostscript or a real GS problem. Then work out a simple way for us to reproduce the issue, and report that to us.

This bug is not a duplicate of 

http://bugs.ghostscript.com/show_bug.cgi?id=691989

Also the call stack is different.

convert is an ImageMagick utility.

Have you tested with the latest Ghostscript release?

I know where convert comes from, we did not develop, nor contribute to ImageMagick. If you can demonstrate the problem using Ghostscript, I'll be happy to reopen this, and investigate. I do not intend to debug ImageMagick convert, too.
