Mathcad Prime 9.0 Crashes for large array.

[Serge.y.Fortin]

When I increase the number of Iteration on page 5, ex. 250 to 2500 the program crashes, instead of giving an error message and stopping.

Confirmed.

It crashes at Iteration=1162, at 1161 all is still well.

Success!

However, there is proof that it will sometimes allow 1162, see attachment.

Thanks for looking at my issues. I tried for several hours to identify which section of the program is at fault without success.

 I had the same issue when using the Graph component. You suggested to use Trace. I could then work for several days without problem. I could run for Iteration up to 20000.

Then the issue reapered yesterday. Again, I removed everything I could but without success.

Additional info: If I reduce the number of objects I can increase the number of iterations. The crash seems to be related to memory management. Still when the program crashes there is no error message.
