"java.lang​.StackOver​flowError" occured when comparing slx models.

Hello.

When comparing Simulink models, "java.lang.StackOverflowError" occured as shown below:

Could you tell me what I should do to avoid this error ?

I guess that this error happens because size of the models I try to compare are too big to compare.

Size of these models is 1.5 [MB].

Actually, when I divide the models into some subsytems to decrease their size and comapre these models again,

This error donen't occur.

What I did to solve this problem:

・Increasing Java heap memory to maximum size: 4077 [MB] ,rebooting MATLAB and comparing models again

・Rebooting PC and comparing models again without launching any other applications

Environment:

・OS: Windows 10 Pro

・Memory: 16 [GB]

・MATLAB: 9.5 R2018b

・MATLAB Report Generator: NOT installed

・Simulink: 9.2 R2018b

・Java: 1.8.0_301

It's OK to answer this question by English or Japanese.

Best regards,
