Questions and postings pertaining to the development of ImageMagick, feature enhancements, and ImageMagick internals. ImageMagick source code and algorithms are discussed here. Usage questions which are too arcane for the normal user list should also be posted here.
Which version of ImageMagick are you using? ImageMagick is theoretically thread-safe. Can you post a program that is ideally less than 50 lines that illustrates the threading problem? We need to reproduce the problem before we can offer any advice.
If we comment out the call to new Image() and delete the program still fails suggesting a logic error somewhere else in the program. When we run the Magick++_Demos distributed with ImageMagick, they all run to completion without complaint. We're using ImageMagick 6.3.0-0.
Our standard suggestion is to open the button workspace, typically in c:\Program Files\ImageMagick-6.3.0-Q16\Magick++_Demo, and build/run it. If it runs successfully, use the workspace as a model for your own custom workspace.
