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
