Hello everyone,
I am blocked on a weird issue I don't manage to solve
We are running a big model which embeds a lot of C code transformed in mex functions, with big buffers allocated on memory in the C code part (up to 20kB).
The first run of this model is perfect. But if I try to run it a second time, Simulink and Matlab crash, without explaining why. It crashes at the 3rd time if using a computer with more RAM (not sure it is relevant, just a note).
If someone could have a idea or an action to avoid this very painful behavior, I'd be very happy...
Thanks in advance

After first run, execute "clear mex" or "clear functions" in MATLAB Command Window to see if it makes a difference.
