New description:

 {{{
 SELECT
 ST_Contains(ST_GeomFromText('LINESTRING(-10 50,50 -10)',4326),
 ST_GeomFromText('POLYGON EMPTY',4326));
 }}}

 The above doesn't always crash the first time but does after second or
 third call.
 -- the actual query that crashed -- the above is a distilled subset but
 there may be more monsters lurking in this query
