Why do I receive a segmentation violation when I use the FEVAL function in MATLAB 7.0.4 (R14SP2)?

I have a program that executes without error in MATLAB 7.0 (R14). I tried to execute the same program in MATLAB 7.0.4 (R14SP2) and upon executing a line that uses the FEVAL function, MATLAB crashes with 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 MATLAB 7.0.4 (R14SP2) that affects the way the FEVAL function is handled.

Currently, you can work around this issue by disabling the Accelerator. To do this, execute the following line of code before running your application:

feature('accel','off')
