I had run a test sequence (Test Harness), via a test file with a blank test suite & a single test case with 2 iterations. The results were visible in the Test Manager Results and Artifacts window and the report started to generate. I think it got to about 60%. Version used is 2016b

Hi, using the 2016b version fix, the error message is now removed and the report generates but even though all the verify statements in the test pass the test report details a failure with the following message:- Simulation Error: An internal error has occurred. Restart MATLAB before proceeding. If this problem persists, please contact MathWorks.
