Same here, on a Mac with GNAT GPL 2014.

(Looking at context in the .mlw file, the line indicated
by gnatprove (showing a VC_RANGE_CHECK of I for  A (I .. A'Last)?)
does not have the .to_int parts present on lines nearby.
I vaguely remember original SPARK conditions referring
to integer supersets. Not that this helps, I guess.)
