Hi this is Abhay Menon, I am facing a problem with r.terraflow module. 

I am using Fedora Core 4 as the OS. also I compiled the module with --enable-largefile switch. and my dataset in ESRI Ascii Raster Grid.

as soon as it starts is generating the watersheds and watershed graph.
the following message is displayed.
