Exact error message is: 

terminate called after throwing an instance of 'geos::util::TopologyException'
  what():  TopologyException: unable to find edge to compute depths at at -200016 249553

In current development version the exception is cought internally triggering a new attempt at buffering with precision reduction, which succeeds.
