Why do I receive a segmentation violation when I disable a linked Stateflow 4.0 (R12) and later chart while editing the library chart?

I copy a Stateflow chart from my library into a new model. I then edit the source chart in the library. The changes made to the source chart are not updated in the chart in the new model. I disable the library link for Stateflow chart in my new model. I receive the following segmentation violation when I try to simulate my Stateflow model:

This problem has been fixed in Stateflow 5.1.1 (R13SP1). If you are using a previous version, read the following:

This is a bug in Stateflow 4.0 (R12) and later in the way that information in a library chart is passed to its linked charts in existing models. There are no known workarounds.
