Crash upon clicking on "AutoCrop"

[Scott Cowles Jacobs]

[... The Hugin Debug window appeared and after describing the situation, I clicked on "OK".
I don't know if the bug info was automatically sent here, or if I was to gather the files and come here and log in and copy the info. In case the latter, here it is... ]

[Copy of Notes.txt follows]
Two input images, one turned approx. 45 degrees from the first (taken from an airplane), "did not complete successfully" I added a bunch of control points, and aligned again, again to get "did not complete successfully". I "enlarged" the "align"ed images in the Fast Panorama preview window, went to "Crop", and clicked on "Autocrop", intending to enlarge the crop window to encompass the entire set of images, when this "Debug report " window appeared.

Following the original crash, I brought up Hugin again, loaded the images again, aligned again
(but did not again add control points and re-align). I immediately went to "Crop", and "Autocrop" again crashed Hugin.

I have not had Hugin crash before.

There is no .pto file, as it never got to that point.

Please provide the pto file before pressing auto crop. The debug log does not really help further.
Load the images, press align and then save the pto file without pressing autocrop.

I'm sorry. I have only ever seen the saving of .pto files as part of the "3:Create Panorama" process, and it never occurred to me that one could do it before then by selecting "Save" from the "Fast Panorama preview" window menu until now...

Here it is...

Thanks for the file.
The main cause for the crash was the big canvas size - this resulted in an overflow in the internal calculation.
This is fixed in the repository and will be in 2021.0 rc1.

A workaround is to reduce the canvas size (currently it is 108276x54138).
