MATLAB: Am I unable to run or compile the embedded MATLAB code when it contains calls to the FFT routine when I select C++ as the target language in Simulink 6.2 (R14SP2)

When I try to run or compile a model which contains an embedded MATLAB block, which calls the FFT routine, I receive the following error:

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 Simulink 6.2 (R14SP2) in the way that the embedded MATLAB block generates and compiles the code containing calls to the FFT routine.
There are currently no known workarounds.
