Comment (by mmetz):

 Apparently v.delaunay worked in grass6.3, so I see 3 options to solve this
 ticket:

 1) Remove v.delaunay and reactivate v.delaunay in v.voronoi. Not that good
 because v.voronoi can do with some maintenance itself and there was a
 reason for the GSoC project (time and memory requirements I guess).

 2) A grass developer working on a Mac digs into the source code of
 v.delaunay and tears it apart until the bug is found and eliminated.

 3) A grass developer without a Mac supplies patches that are tested by
 others with a Mac. Will take some time.

 Going for 3), please try the updated patch. Before applying the patch, all
 files in v.delaunay2 must be deleted if the previous patch was applied,
 then svn up. Just for the record, run make | grep warning to see if the
 Mac compiler has some complains (Linux gcc doesn't). Then apply the patch,
 make and grep warnings, test patched v.delaunay if no compile warnings or
 errors occurred. If this patch still doesn't fix it, I am at a loss.
