Short description of error
I have created an animation with the addon animation node
when i render the animation, after 3-4 frames, the current rendered frame result not appear and after maybe 1-2 frames, blender is crashing
i got the error EXCEPTION_ACCESS_VIOLATION in the console (the console disapear quickly after blender crash, i use a video for read the message.)
i have visual studio installed ,but the system not propose me to debug the crashed app. (it propose me one time when it was a freeze, but never succesd to have again this freeez. i got only crashes now)
i had this bug in 2.8 rc1 but always in 2.8 rc3 (donwloaded today)

Gets to around displayed countdown image of 21 / frame 27 here then crashes. Switching it to 8 samples 25% output frame size and Cycles CPU+GPU causes it to render counts differently, it crashed after frame 7 having displayed 0, 0, 2, 2, 5, 5 in the rendered frames. Restarted it and did the same thing and it did *not* do the weird number duplicate/skipping (it did skip a number around 27 or 28) then crashed after frame 35. All very non-deterministic.

I was unable to get Animation Nodes to load into my debug build, so didn't get any backtraces.

yep its weird. i dont understand how a addon can crash blender (i thought blender can stop not good request for mesh generation) , but i thinck its due to the addon animationNode.
maybe a delay during rendering between last generation and current
I have tried with another anim and its ok for rendering one frame, but when rendering anim, some generated mesh are missing, and blender crahs a some seconds after.
I will tried to have a blender porject to debug

I merged this into the task that is probably the root issue. Unfortunately, there is not a good solution for it currently. Maybe rendering individual frames from the terminal works, but it's not an ideal situation. Other addons have similar problems.

Note, generally bugs in Animation Nodes should be reported here: https://github.com/JacquesLucke/animation_nodes/issues

ok, i was not sure if it was a bug of your addon of a bug in blender.
because i tried to load my file in a debug version of blender, and each time i launched the rendering of an animation, i got a ACCES_VIOLATION_ERROR after ctrl + F12 or F12

but the rendering started after i clicked on the button continue in visual studio. but the error occur after each frame..

thanks
