 Hello to all,

 First of all thank you all for the great work you are all collectively
 doing, I'm very often impressed by the power of open GIS.

 I have been struggling with a problem on Grass 6.4.3RC1 and 6.4.3RC2 with
 the v.overlay.and function.
 I tried to clip a line network on a single polygon, and the output is
 wrong : some lines are missing, some lines are there that should not be.
 The problems occur with lines that intersect with the polygon's boundary.

 I tried with different sets of data, and with simple features I created
 for the test in Grass. Same wrong results.

 I tried to use the same data with Grass 6.4.2 on my computer and on other
 computers runnig 6.4.2 and it worked on all PCs.

 I tried to upgade one PC in 6.4.2 to 6.4.3 and did the same test :
 v.overlay.and produced the same erroneous output.

 NB : I setup Grass 6.4.3 on my PC through osgeo4w, and 6.4.2 through the
 windows standalone installer. I also just tried with the 6.4.3.RC2
 standalone installer and the output was also wrong.

 If it wasn't for my boss, I would switch from Windosw to the Dark Side of
 the Force...

 Can someone else test this function in 6.4.3 ?
