Comment(by strk):

 Kind of crazy, I created a table with the result of the subquery, getting
 2 records with g1/g2 and could reproduce the crash using ST_SharedPaths
 against g1,g2 of first record.

 Those geometries I've put in the regression test and can't reproduce the
 issue.
 I wonder if it's a corruption somewhere else.

 Look at this:
 {{{
 strk=# select st_sharedpaths(g1::text::geometry,g2::text::geometry) from
 bug670 where id = 1;
 ERROR:  GEOSIntersection: IllegalArgumentException: Geometry is not lineal
 strk=# select st_sharedpaths(g1,g2) from bug670 where id = 1;
 server closed the connection unexpectedly
         This probably means the server terminated abnormally
         before or while processing the request.
 The connection to the server was lost. Attempting reset: Failed.
 !>
 }}}

 Note that ::text givesn HEXEWKT, so there should be nothing lost.
 I suspect there's some corruption in internal structures _before_
 SharedPaths is invoked.
