upgraded to 1.0.4, still the same. PostgreSQL was compiled with
--enable-cassert, but does not report any problems at all:
testdb=# select pointn(line, 2) from test;
("line" is a 4D geometry with about 800 points)
Program received signal SIGBUS, Bus error.
0x7107a660 in ?? ()
#0 0x7107a660 in ?? ()
#1 0x7107a610 in ?? ()
Previous frame identical to this frame (corrupt stack?)
(postgres, as said before, does not report anything)
looks to me like something while traversing the geometry goes horribly wrong
here. how can i help tracking this down? start printf debugging?
