This is the first time I noticed the problem, but I haven't used
v.delaunay in a while. I tried the command modification you suggested,
but with the same outcome. I also went back and recompiled a svn
checkout from about 1.5 months ago as a 32 bit app, but v.delaunay
behaved identically. I'm not sure whether v.hull and v.voronoi share
much of the same code or not, but they both run fine.

I don't see any changes in v.delaunay itself from RC4, though maybe
there are changes in the vector libraries. Did this work in RC4?
A big difference in RC5 for OSX is that it's now 64bit. Does this
work:
arch -i386 v.delaunay in=DelaunayPoints out=DelaunayTriangles

Hi,

I've tested it on the same machine running Linux and had no issue.
It also ran without issue on Mac OS X with GRASS 6.3. Can anyone
verify that it isn't working properly anymore or could it be a
problem with my installation?
Cheers,
