 Replying to [comment:3 mlennert]:
 > I backported to release70. r67922
 >
 > The issue is not present in 6.x.
 Yes, sorry, I didn't check the code in careful way. Issue is present only
 in 7.0.0 release.

 > > 2) A clarification on potential impact should be provided to allow
 endusers to evaluate potentially affected results of any analysis
 performed with 6.3-7.0.
 > This would be important to understand in order to explain the impact.
 Also: where do want such an explanation ? A mail to grass-user and grass-
 dev ?

 Looong time a go (Mon Nov 12 00:49:58 PST 2012) I made a proposal(1) on
 establishing guidelines how to handle situations when we discover code
 producing good looking but erroneous output (type II error) or corrupting
 existing data in other silent way. At the moment such issues are
 documented in issue tracker and intermixed with other discussions on -dev
 ML thus not providing an easy way for data quality issue tracking for
 outsiders (ordinary users). Probably it is necessary to revisit my idea
 and then decide to close this issue or not (as the problem with code has
 been fixed).
