I've got another weird crash that happens when I try to start my scene after I added a vision sensor. It's just that. I start my scene, it works, I stop it, add a vision sensor, start it again and V-REP crashes with a segmentation fault.
You can clone the scene from our GitLab instance for investigation purposes if you need it:
We tested two of your scenes (11/17 and 10/27), and both run fine on Windows. Under Linux however 11/17 can lead to a seg fault, but this is not a direct consequence of the vision sensor (i.e. simulation continues running for a while, before crashing). Can you narrow the problem down (e.g. by simplifying your scene to a maximum), in order to make sure your code is ok?
Debugging V-REP with a complex scene can become a difficult challenge sometimes ;)
can you tell us what Linux you are running?
In any case, there will soon be a new V-REP release (V3.1.0) that has a heavily modified base architecture, hopefully that will be more stable.
I'm using Ubuntu 12.04 LTS. I have found the problem. If you have a ATI Video Card, your system crashes.
I have tested my vrep scene with a NVIDIA card and all works.
