DESCRIPTION

I am in the process of trying out UmlGraph, and using the resulting dot files in GraphViz to generate png files. I have noticed however that I can fairly easily cause GraphViz to crash in this process, when the dot file gets complicate. I have not been able to identify any pattern for when this will happen.

STEPS TO REPRODUCE

I am running the following CLI command to cause the crash:

dot -v -Tpng -oUMLPcmEngineBlueprintView.png UMLPcmEngineBlueprintView.dot

ADDITIONAL INFORMATION

There are other inputs that I can generate which also cause dot to crash. Hopefully howver the file that I attached is representative of all of them.
