Comment (by Lars Aksel Opsahl):

 With test_01.sql this happens I do get topology errors.

 {{{
 psql:/tmp/test_01.sql:52: ERROR:  Side-location conflict: new edge starts
 in face 117 and ends in face 0
 psql:/tmp/test_01.sql:68: ERROR:  Side-location conflict: new edge starts

 psql:/tmp/test_01.sql:354: ERROR:  Side-location conflict: new edge starts

 }}}

 And the result topology reports this errors


 {{{

  ("mixed face labeling in ring",-667,)
  ("mixed face labeling in ring",-666,)
 (2 rows)

 }}}

 But the server does not core dump.
