MATLAB: Do I receive a segmentation violation when I execute a Stateflow chart containing objects of size “0” in Stateflow 6.1 (R14SP1)

0chart;dataobjectscalarstateflow

I have defined the size of a few Stateflow data objects to "0". When I try to execute this Stateflow chart, I receive the following segmentation violation:

This bug has been fixed in Release 2006a (R2006a). For previous product releases, read below for any possible workarounds:
This is a bug in Stateflow 6.1 (R14SP1) in the way it handles empty matrices.
To work around this issue, perform the following steps:
1. Open the Stateflow model.
2. Execute the following command to change all the data objects which have a "0" size to a "1" size, which denotes a scalar:
sf('set',sf('find','all','data.props.array.size','0'),'data.props.array.size','1')
3. Save the model.
