I spent some time looking at this, and I realized that you had actually
done some work on the error reporting, but they aren't picked into the 1.4
branch:
https://github.com/OpenImageIO/oiio/commit/73af64b64867785e8c1ccca1ad3a8dff87777f0e
https://github.com/OpenImageIO/oiio/commit/65eeee465edf030867ed7468632a5e6dcadfbb5b

I see that you now have an error() function that exits non-zero, and it
gets called in the output logic when there is a write error. Can this stuff
get merged into 1.4?
