Thank you Evan for your kind proposal. I am sure that you have more useful things to do for the community and I would not dare asking for a personalized assistance. Yet, if you believe that my problem could be a general interest, I would be glad to provide a clean example project that crashes.
I take this opportunity to send many thanks and congratulation to all your MIT team for the great job.
I may have a clue about the origin. I have noticed that a weird media file has appeared in my MEDIA folder when I was writting blocks in a new screen (see attachement) or when I was testing the project. When I delete this "media" file, the error message from the compiler is not longer empty (and this allowed me to spot the problem in my code).
I now speculate on the origin of this Media file. Could it have appeared when I defined a very long global variables (copy-pasting a string of more than 120000 chars), producing some overflow somewhere ?
I have finally solve my problem the following way :
- I reduce the length of the long string to roughtly 80000 chars
- I exported the newest screen the current project into an old archive of this project using the great AI2MergerApp.jar tool.
