Comment(by strk):

 I've spotted this into the logs:
 {{{
  snap/LineStringSnapper.cpp:349: void
 geos::operation::overlay::snap::LineStringSnapper::snapSegments(geos::geom::CoordinateList&,
 const ConstVect&): Assertion `pf != 0.0' failed.
 }}}

 Reviewing the code actually seems to suggest there's a bug in GEOS, but
 for some reason I can't reproduce it with a geos-only input !?

 Can you isolate a simple offending case ?
