OutOfMemoryError with pose branch

[TomGrimwood]

Using the pose branch, when the image stream begins, I receive this error;

I am using an Nvidia Orin with OpenCV 4.5.4, ROS Galactic.
If you need any further information let me know.

Well, I guess your Jetson Orin does not have 117094104464640 bytes of memory :-)

It's unclear to me why this happens. I assume that at some point the image dimensions are wrongly calculated or there is an integer overflow.

Do you see this issue only on the pose branch? Can you provide a rosbag to reproduce this and/or a gdb backtrace?

[christianrauch]

@TomGrimwood Can you clarify if this only happens on the pose branch? Can you provide a log file to reproduce this? Alternatively, can you provide a backtrace with source code line numbers and the commit at which this happens?

[TomGrimwood]

Sorry it's been a while. I think it was related to the OpenCV cuda enabled build that came with the Orin. I am unable to check if I can reproduce this behaviour.
