 v.buffer2 (not original v.buffer) produces warning messages on Linux 64bit
 that are not apparent on Linux 32bit. The initial results differ slightly,
 the final result seems to be ok after lots of cleaning.

 Reproducible with roadsmajor in nc_spm:

 {{{
 GRASS> v.buffer2 input=roadsmajor at PERMANENT output=roadsmajor_buf1_2000
 distance=1000

 WARNING: Next edge was visited but it is not the first one !!! breaking
          loop
 WARNING: Next edge was visited but it is not the first one !!! breaking
          loop
 WARNING: Next edge was visited but it is not the first one !!! breaking
          loop
 }}}

 No such warnings, but topological errors with distance=500, warnings like
 these but no topological errors with distance=1000 or larger.
