Comment (by pramsey):

 Based on the example provided, here's the minimal crasher, which could be
 tested in GEOS.
 {{{
  select st_intersects(
  'LINESTRING(10 0, 0 0, 0 10)'::geometry,
  'MULTILINESTRING((10 -1,-1 10),EMPTY)'::geometry
  )
 }}}
 Just having the collection-with-empty structure was not enough to induce a
 crash, the geometries had to overlap so that the overlay code was started
 up. Then things went boom.
