Why does MATLAB 7.0.1 (R14SP1) crash when I make an incomplete function call while using the Image Acquisition Toolbox?

I am using the Image Acquisition Toolbox with MATLAB 7.0.1 (R14SP1). After I open my video input object, I changed its 'ReturnedColorSpace' property. Then I tried to evaluate an incomplete command such as :

corr2(frame1,fra

where 'frame1' is the image returned from my SNAPSHOT function. At this point, MATLAB crashed with the following error message:

 ------------------------------------------------------------------------

              Assertion detected at Tue Oct 12 14:14:57 2004

 Assertion failed: hdr->in_use != 0, at line 736 of file ".\memmgr\memcache.cpp".

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

We have verified that there is a bug in MATLAB 7.0.1 (R14sp1) in the way that MATLAB handles incomplete function calls which are executed using the "Evaluate Selection" option. There are currently no known workarounds other than refraining from making incomplete function calls.
