MATLAB: Does MATLAB R2017a crash when I save and reload a Simulink.MDLInfo object

MATLABsl_loadsave_mcos.dllsl_services.dllslsvstring

I am trying to save and reload a Simulink.MDLInfo object using a MAT file:
mdl_info = Simulink.MDLInfo('vdp.slx');
save('test.mat');
load('test.mat');
mdl_info
After reloading the MAT file into workspace and trying to access a method of the Simulink.MDLInfo object, MATLAB R2017a crashes with stack trace below:

Best Answer

This is a bug in MATLAB R2017a (and earlier) that was fixed in R2017b.
To work around the issue, convert the object to a struct before saving it:
mdl_info = struct(Simulink.MDLInfo('vdp.slx'));
save('test.mat');
load('test.mat');
mdl_info
