Markus M.
Thanks once again for the advice. I updated to the most recent version
yesterday and tried v.buffer again but it ran out of memory at around
the 75% complete mark during the snapping boundaries step. I only have
5.7 GB physical memory and 5.7 GB swap available. I tried r.grow and
that appears to have worked just fine. It took about 10 hours but I'm
not in a rush so that's fine. I look forward to testing the GRASS 7
version of v.buffer when that is working.
All the best,
Ned

Thanks for the help compiling with v.buffer. I think I'm running the correct
version now but the function still does not complete properly. I pasted the
last several lines from the terminal screen below. I have a feeling I ran
out of memory. Any ideas about what I can try next?
Not sure if the "d.vect: free(): invalid" error means that d.vect
caused the problem.
You could try several things:
- update your grass-6.5 to r45873
- close the grass gui and other applications not really necessary
- now try v.buffer again
The process got killed while snapping boundaries which is rather
memory demanding. Memory consumption for vector operations like
snapping can be substantially reduced in grass 7, but grass 7 still
has only the broken version of v.buffer2 (to be fixed).
Alternatively you could use r.grow.distance on the rasterized version
and set all values larger than the desired buffer distance to NULL

If you ran make in the v.buffer directory and afterwards configure,
make and make install in /usr/local/src/grass6_devel, you would end up
with v.buffer2.
1. run configure, make, but not make install in
/usr/local/src/grass6_devel
2. run make in the v.buffer directory, watch out for errors to make
sure it compiles all right
3. run make install in /usr/local/src/grass6_devel, but not again
configure and/or make
4. that should give you the original v.buffer
An alternative: simply modify
vector/Makefile
to point to v.buffer and not v.buffer2...
