GMT Movie frame size

It appears as if movie has lost the ability to use non-integer frame sizes in 6.6.0. I just updated from 6.5, and I now get the error
“movie [ERROR]: Option -C: When either a +c or +i modifier is used, dimensions must be integer pixels”
when setting gmt movie main.sh -C24cx14cx160+c. This would normally be the 16:9 size, but it doesnt like it when i try to specify that either via gmt movie main.sh -C16:9.

On another note, I cant seem to be able to run gmt grdimage $filename1 -R$region -J$Jparam -I+d -C$CPT_FILE -Y2i -X0.5i within my movie scripts without getting
“*** buffer overflow detected ***: terminated
movie_preflight.sh: line 47: 385886 Aborted (core dumped) gmt grdimage $filename1 -R$region -J$Jparam -I+d -C$CPT_FILE -Y2i -X0.5i”

I think that the modifiers +c and +i were added after 6.5. So, I would suggest you to remove +c from the -C option.
