OpenCV "contours" node crashes latest previews

hi all,

preview 627. gamma instantly crashes if I open one of the examples. did not try all, but multiple.

please be more specific:

  • which version of VL.OpenCV
  • which exact example

vl.opencv 2.1.0

examples:
how to detect shapes
extract contours
apply a mask to an image

i’m afraid, cannot confirm. opening all 3 in parallel and closing one after the other. no crash. hm…

ok different behaviour on different pcs, all win10
preview 627 and vl.opencv 2.1.0
latest intel and ryzen chipset drivers
nvidia studio driver 472.47

gamma crashes when opening the following helppatches:

PC1: Ryzen7 + GTX1080ti
how to detect shapes
extract contours
apply mask to an image ### working after driver update

PC2: Ryzen7 + RTX 4000
how to detect shapes

PC3: Intel i7 Gen4 + RTX4000
how to detect shapes
extract contours
apply a mask to an image

PC4: Intel i7 Gen7 + P4000
how to detect shapes
extract contours
apply mask to an image

PC5: Intel i7 Gen7 + P3000
all three examples work

Error logs avaliable if needed, Different Errors for every example but all of them point to OpenCVSharp more or less.

Post logs, there is nothing else that can shade a light…

what’s the driver situation on those 5PCs? do they all have the same/latest?

@schlonzo check the windows event viewer.

@joreg Maybe you could make a sticky “How to post bug reports” since this comes up time and time again.

I checked the first two, both run the latest amd chipset and nvidia studio drivers.
Please find the error logs in the attatched zip file.

The “contours” node seems to be the culprit.
When I delete it the patches run fine.
