[GRASS-user] v.delaunay Bug in Mac OS X

[Michael Perdue]

Hi,

v.delaunay is generating incorrect results on Mac OS X on my machine  
(Intel Mac Pro, Leopard, W. Kyngesburye's GRASS 6.4-RC5 binaries). The  
following commands give the results below;

echo "456490.2375|5905949.8625|1

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,

Mike
