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
