Comment (by robe):

 strk,

 And for your info.  Evidentally Paul is running 8.3 too if you look at his
 gdb output up there he is running 8.3.8.  What's odd now is that mine is
 not crashing after I recompiled GEOS and PostGIS with CFLAGS="-g -O0".
 But I am getting 2 regression failures now

 One on measures and one on clean.

 I first installed the clean.sql in my postgis db and then ran that single
 command Paul had above


 {{{
 echo "select st_astext(st_makevalid(orig)) from clean_cases where caseno =
 3;" | valgrind --leak-check=yes --log-file=valgrind.log
 /opt/PostgreSQL/8.3/bin/postgres --single -D /opt/PostgreSQL/8.3/data -p
 5433 postgis
 }}}


 Doesn't crash -- but valgrind gives
 See next attached file.  Its all greek to me.
