[GRASS-user] v.generalize crash

Hi all,
I get consistent crashes of v.generalize on Debian sid, official deb, e.g.:

GRASS 7.0.3 (world):~ > v.generalize input=corine@PERMANENT layer=1
type=area type=line,boundary,area method=douglas threshold=5.0
look_ahead=7 reduction=50 slide=0.5 angle_thresh=3 degree_thresh=0
closeness_thresh=0 betweeness_thresh=0 alpha=1.0 beta=1.0 iterations=1
output=corine_simpl

Same with different options and data.
Does anyone confirm?
Thanks.

Hi Markus,
that was fast, thanks. When is 7.0.4 scheduled? Given the crash, I
believe having fixed packages soon is highly desirable.
All the best.

Sure - here is our release schedule:
https://trac.osgeo.org/grass/milestone/7.0.4

In some weeks we'll have the first RC. Some more known bugs to be
eliminated since then!
