Crashing Arena with a QC source

[flo]

Hi folks,

recently I ran into crashes caused by some quartz-composer sources which I use to generate text in resolume arena.
To reproduce the crashes, load the attached qc-file in a layer or in the preview monitor and for example pull the kerning-slider to maximum and... crash! There are other combinations of parameter-values that can cause the crash but this one seems the easiest to reproduce.
This happens in the actual arena version (5.1.2) but also in arena 4.1.6.
I am not a qc-guru, so maybe the qc-progrmaming can be done avoiding to crash arena, but I don't know how to do so.

Regards

No problem running this in 5.0.1 in my quick test.
Nothing about the composition seems awry to me when opened in QC.

Works for me as well on 5.1.2.

Btw, it looks like you're using this to make a horizontal scroller. If that's the case, you can use the Display Width output of the image created by the Image With String patch to see how wide the text is. Then you can calculate the limits of the X Position value to make sure the animation starts exactly off screen left and ends exactly off screen right.

I can replicate the crash on 5.0.2 as well as on 5.1.2,
2012 mpb, gt650m, El Capitan.

Here's the relevant part from the log:

The important thing to note that QC crashes, and then takes Arena with it. Recursive rendering would imply that it crashes in the blur pass.

[flo]

Thank you all for your testing and the answers.
So it could be a that the qtz-file has an error and causes the crash?
In my testing I realized, that the crash happens when the video memory is nearly at capacity limit. Could that cause the crash?

I removed the blur from the signal path and I couldn't get it to crash.
There is a blur effect in resolume you could throw on the QC clip.

[flo]

Gold idea, to remove the blur. I'll try that later.
