Dear maintainer,

I believe there is serious [critical, imo] bug in regionprops 'boudingbox'. 
Here is a sample test
case: 

    save the attach script, chmod a+x;
    save the small test mask image and
    run:

        bb-test . sm-mask png

    the results speak for themselves.

Here below the set of values per octave/octave-image version [availble in the
debug session,
copied here to help

#{

3.6 - 2.0.0-3: stats(i).BoundingBox
ans =    0.50000   36.50000   39.00000   64.00000
x1 =  1
x2 =  39
y1 =  37
y2 =  100

3.8 - 2.2.1-1: stats(i).BoundingBox
ans =    0.50000   70.50000   32.00000   50.00000
x1 =  1
x2 =  32
y1 =  71
y2 =  120
