  Priority:  major   |  Milestone:  7.0.5
 Component:  Vector  |    Version:  7.0.4
Resolution:          |   Keywords:  v.generalize
       CPU:  x86-64  |   Platform:  MSWindows 7

Comment (by dido):

 OK, I will close the issue due to the fact that an algo rework of
 v.generalize not to leave too long non-generalized boundaries behind will
 be too costly to be implemented.

 Still this particular use-case needs a good explanation in the
 v.generalize manual. I could not find any clue that the generalize
 algorithm will simply stop and retain the boundary untouched IF any
 topology damage occurs during processing. The good workarounds must also
 find a way to the manual -- to slice-down the input adequately, then to
 apply v.generalize and v.dissolve, or to apply multiple v.generalize steps
 with increasing distance.

 Regards,
 Dido
