[GRASS-user] r.in.xyz: *** glibc detected *** double free or corruption

[Patton, Eric]

Although I seem to now be able to *open* large files with r.in.xyz, it
inevitably crash about 15 minutes into the gridding of a 2.8GB xyz file,
every time.

Here's the output from gdb:

(gdb) r.in.xyz input=2006MB_GarryTrough_2.txt output=2006MB_GarryTrough_2
fs=space
Starting program: /opt/grass6/dist.i686-pc-linux-gnu/bin/r.in.xyz .in.xyz

I may need some pointers on using gdb, as this is my first time. But
hopefully this backtrace will be useful.
