Why do I receive a segmentation violation when using TEXTSCAN with MATLAB 7.0.1 (R14SP1)?

When I call TEXTSCAN in the following manner:

textscan([]);

I receive the following segmentation violation:

This bug has been fixed in Release 14 Service Pack 3 (R14SP3). For previous product releases, read below for any possible workarounds:

We have verified that there is a bug in TEXTSCAN that affects the way it handles an input of an empty matrix. To work around this issue, call textscan with a non-empty input.
