d.vect: segfault if zcolor= does not exist

Reported by: hamish Owned by: martinl
Priority: major Milestone: 6.4.0
Component: Default Version: svn-develbranch6
Keywords: d.vect Cc: grass-dev@…
CPU: x86-32 Platform: Linux

Description

Hi,

a typo causes a segfault in d.vect:

v.random -z out=rand2k n=2000 zmax=1000
d.vect -z rand2k zcolor=bcry
Segmentation fault

(should have been zcolor=bcyr)
