Comment(by pramsey):

 Sorry, no help from me. Clearly some function somewhere is dropping SRID,
 but I don't see any obvious candidates in the PL/PgSQL and unrolling that
 amount of Pl/PgSQL is beyond me. The fact that it's only failing for
 npoints > 3 might be useful in finding the issue, though who knows: why do
 you get differences between 2.0 and 2.1 on the result for 3 point lines?

 Maybe this requires the Mother of All bisections to find the change point
 wherein the result of this function changed.
