Why is SUBSASGN not casting to DOUBLE properly in MATLAB 6.5 (R13)?

I have created object with an overloaded DOUBLE and SUBSASGN methods. This used to work in MATLAB 6.1 (R12.1).

For example:

y = eye(2);

x = myclass(1,1);

setmyclass(x,1234)  % assigns a numerical value to the myclass object x

y(1)=x;

MATLAB 6.1 (R12.1) gives the following output :

 y =

         1234       0

                0       1

MATLAB 6.5 (R13), however, errors out when I try to execute the "y(1)=x;" statement:

 ??? Conversion to double from myclass is not possible.

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

This is a bug in MATLAB 6.5 (R13). As a workaround, use explicit data conversion.
