Comment:

 I do confirm the bug, but couldn't find the time to produce a testcase for
 it.
 It doesn't seem an easy case, possibly affected by a bug in ST_Intersect
 or something
 like that.

 Commit r8941 simplifies the code and fixes the bug for me.

 The existing testcase (test/regress/st_addisonode.sql) was hard to
 understand so I rewrote it with r8942
