I am not having this trouble:

    $ VHEIGHT=$(ffprobe -v 0 -of compact=p=0:nk=1 -select_streams 0 \
    -show_entries stream=height 'The Master (2012).mp4')

    $ echo "$VHEIGHT"
    1040

but as Marco said, you might need to sanitize for carriage returns:

    $ echo "$VHEIGHT" | od -tcx1
    0000000   1   0   4   0  \r  \n
             31  30  34  30  0d  0a
