Comment(by jczaplewski):

 I upgraded to 2.1.3 and narrowed it down to some problematic geometries.
 Basically, I LIMIT 10 with an offset, and if I do
 {{{
 ST_Intersects(geom, (SELECT buffer FROM linestring))
 }}}

 I get the BOOM! error. However, if I wrap the geometry in an
 ST_MakeValid() I do not:

 {{{
 ST_Intersects(ST_MakeValid(geom), (SELECT buffer FROM linestring))
 }}}

 Would you like me to pass along the problematic geometries for debugging,
 or should we consider this resolved? Thanks for your help!
