> Strange. Topology building should be much slower with
GRASS_VECTOR_LOWMEM, therefore I would expect v.build with
GRASS_VECTOR_LOWMEM to fail later, not earlier. Can you provide data and
commands for testing?
Data and info provided via private mail.
Previous posters have also reported that setting GRASS_VECTOR_LOWMEM
didn't make much of a difference, so maybe the problem is there ?
