Hello, my GRASS version is GRASS 6.4.0 (2010) (from launchpad repo) on Ubuntu 10.10 At this address http://dl.dropbox.com/u/362123/testing_location.tar.gz you can download my testing location. Inside the mapset you have only one vector line outputted from v.net Try to run this command: v.net.iso --overwrite input=streams_net output=myriver type=line nlayer=2 ccats=1 costs=100,300,2000 I have this error: Generating isolines... *** glibc detected *** v.net.iso: malloc(): memory corruption: 0x092cc3e8 *** ======= Backtrace: =========
