Running regression tests against PostGIS from current trunk (r4706) gives failure for the hausdorff test

hausdorff. failed (diff expected obtained: /tmp/pgis_reg_25454/test_44_diff)

and it looks it crashes the server

I did full rebuild of both, PostGIS and GEOS.

Environment:

  • Linux 64-bit (Ubuntu 9.10 Karmic Koala)
  • GCC 4.4.1
  • GEOS (version 3.2.0 from SVN trunk 2710)
  • libxml2 2.7.5

I wonder if this is related to #258 though Mark had fixed this and I believe he is running 64-bit so must have worked for him.

Can you check (ST_LineCrossingDirection) http://www.postgis.org/documentation/manual-svn/ST_LineCrossingDirection.html

Since that had similar issues too. I haven't tested against the latest GEOS trunk so that might be something else.
