[GRASSLIST:2261] r.thin instability

[Christopher Fonnesbeck]

I have been trying to run r.thin on a 30000x30000 raster in order to 
develop a stream network, but am suffering instability problems on 3 
different machines. On 2 linux boxes, I get an error writing a 
temporary file, while on an OSX machine I get a bus error. All machines 
are running GRASS 5.7 compiled from a very recent CVS. Does anyone have 
experience with either of these errors and how to circumvent them?

Thanks,
Chris Fonnesbeck
