[colorforth] XcolorForth crashes on read or write to frame buffer.

["Samuel A. Falvo II" <kc5tja@xxxxxxxx>]

I'm trying to plot some points to the display, and unfortunately, any 
write to the frame buffer segfaults the executable.  It also appears 
that reading from the framebuffer also causes a crash.

Here is my code (in punctuated form):

: px over ! 4 + ;
: r $FF0000 px ;
: g $FF00 px ;
: b $FF px ;
: rgb [ frame ] r g b ; rgb

(Note: [ XYZ ] indicates that XYZ is yellow.)

Any ideas as to why this is happening?

Thanks for the help.
