I'm assuming a byte-by-byte file compare won't suffice? In which case
perhaps just extract the text -(something like PDF2TXT / PdfGrabber
[google hits, NOT a recommendation]) and compare that.

Note that the same document could be expressed in very different
markup, so it might not be trivial. Also note that if the copy is in
images you could have problems, especially if those images are not raw
bitmaps, as it could be very hard to spot real changes.

Why don't you do a MD5 has of both files and then compare that?

I have an application I created called "JpegViewer.exe". It simply loads a Jpeg file and displays in on the screen. It works great, in my lab. When I am using it at a customer site, things change. Occasionally, it blows up with an Application Exception. It seems to only die at the customer site

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
