Why does MATLAB 7.0 (R14) crash when I use the SYSTEM_DEPENDENT function without any input arguments?

When I use the SYSTEM_DEPENDENT function without any input arguments, as in the following:

system_dependent

I receive the following segmentation violation:

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 MATLAB 7.0 (R14) in the way that MATLAB handles the SYSTEM_DEPENDENT function.

Using SYSTEM_DEPENDENT without input arguments is incorrect syntax. It should always have at least one input argument.
