Hi Julien,
FYI, it was in fact a bug in opencv:
https://github.com/Itseez/opencv/commit/ebd7d08408205aebb478af1e6239f9c2e4dc2fdd
To solve this, cuda and opencl is now deactivated in OTB Superbuild:
https://bugs.orfeo-toolbox.org/view.php?id=1084
The patch is available in branch release-5.0 and will be also available
in the next OTB release (branch develop).
Best regards,
Manuel

I am trying to compile OTB on ubuntu with OpenCV ON (OTB 5, superbuild).
It works when I disable OpenCV, but I have a CUDA error when I enable it.

Any idea where this could come from ?
