Photoshop CC 2015.5 failure:

Resized a 300 M-pixel image and Ps got very, very confused

However, after exporting full size and using Mac's "Preview" to resize it, it works:

What OS/version are you running on?

Are you using Image > Image Size... to resize the image? or a different command?

What are the dimensions, color mode and bit depth of the image you're starting with? (can you post a screen shot of the dialog before you make any changes and the dialog box after you've entered your settings?

OS/X Sierra aka 10.12 aka Darwin Kernel 16.0.0
The Photoshop CC version is whatever was up-to-date yesterday.  Today, it updated itself.  I used Ctl-Cmd-I to invoke "Image Size".

The image size was 300 mega pixels.  16 bit color depth.  "color mode"?  I was using
Nikon raw (.NEF) for source, but assembled 20 images into a pano.  OK, it just finally
got back up:  Image Size: 3.39G  83367X7273  The 300MP number came from "Preview".
I guess even the "full resolution" jpeg was 1/10 size.

I have no idea how many resizing commands Photoshop supports, but I would surely
hope that there is only one algorithm for doing the job.

Since this is a reproducible issue, send me (privately) anonymous FTP instructions
and I'll upload my .PSB file.

Before we go through uploading the file, can you tell me if your document was a flat background, or was it still layered/masked when you did the resize in Photoshop?

It should have been, but I'm not 100% sure it was.  There was only one layer, but when I moved around quickly or did other operations that triggered multiple refreshes, I was able to see some of the editing steps.  So, apparently, despite saving and reloading the project, some of the editing process remains in the .PSB file.  From a naive user perspective, yes, it is flat.
