Hi,

I just found a rather interesting bug that has been eluding me for the
last 2 years! This code should crash IDL for windows, versions 6.1,
6.4 and 7.0. I've created an incident with ITT support.

pro rkbroitest

oWindow = obj_new('IDLgrWindow')
oView = obj_new('IDLgrView')
oModel = obj_new('IDLgrModel')
oView -> add, oModel

oROI = obj_new('IDLgrROI')
oModel -> Add, oROI
for i=0,1000 do begin
len = i+1
for j=0,len[0]-1 do begin
p = randomu(seed,2)
p = 2*p-1
oROI -> AppendData, p[0], p[1]
endfor
oWindow -> Draw, oView
oROI -> GetProperty, N_VERTS=n_verts
oROI -> RemoveData, COUNT=n_verts

endfor
obj_destroy, oROI
obj_destroy, oWindow
end
