What steps will reproduce the problem?
1. Create two slightly different ~5GB files on Windows XP SP2.
2. Run xdelta3 -evv -s file1.bin file2.bin file2.vcdiff

What is the expected output? What do you see instead?

Expect to get a difference file in file2.vcdiff, however, I get this error 
instead:

What version of the product are you using? On what operating system?


Please provide any additional information below.

Version 3.0h running on Windows XP SP2. File1.bin did *not* change during 
the run of the program, despite the error reported by xdelta3. I will re-
run to confirm.
