When i start the solver i have this assertion window.
Please,i want to know what this assertion mean!
You are using an old version and the line numbers do not correspond. Probably you have a subgroup which has to attend 2 activities at the same time - a broken basic time constraint.
Please can you look at the sample,when i try to activate the last activity, i will have in result generation the "assertion window"!
I tried with my latest version (FET 5.9.1) and everything is OK, just it does not solve.
I see that you have FET version 5.6.0. Maybe I fixed this crash bug in later versions, please update your software.
