This now crashes

julia> bar(rand(15), color=:rainbow, show=1, Vd=2)
"psxy  -JX14c/9.5c -Baf -BWSen -R0.4/15.6/0/0.94 -C -i0-1,1 -Sb0.8u+b0 -P -K > C:\\TMP\\GMTjl_tmp.ps"

Very likely it's because it can't handle the -i0-1,1 anymore. The crash is indeed caused when it tries to access a 3rd column in data that has only 2 columns
