Why do I receive a segmentation violation when I generate code in the presence of charts with "Execute (enter) Chart At Initialization" turned on with the Stateflow Coder 6.0 (R14)?

A crash occurs during Real-Time Workshop code generation if the model contains a chart with the "Execute (enter) Chart At Initialization" property (under Chart Properties) turned on and if the chart also calls an exported graphical function from another chart. The error is similar to the following:

This bug has been fixed for Release 14 SP1 (R14SP1). For previous releases, please read below for any possible workarounds:

We have verified that there is a bug in the Stateflow Coder 6.0 (R14) in the way that it handles code generation with the "Execute (enter) Chart At Initialization" property turned on and if the chart called an exported graphical function from another chart. There are currently no known workarounds.
