Mike, PostGIS 1.3.3 has been pretty stable for me on Windows XP, Windows 2003 and Red Hat EL Linux.
Though I can't say I have ever tried using disjoint since there are much more efficient ways of checking for disjointedness than using disjoint. Buffer(..0) I have used a fair amount though and haven't run into any issues. Though I have had some issues when using - values for buffer. Which version of Geos are you running? I suppose you could be running an unstable version of Geos. The latest stable release of geos is 3.0.0 which you can determine if you are running or not with the command. select postgis_full_version(); 3.1 and 3.0.0 rc 3 and before I believe are somewhat unstable. I think 3.0.0 rcs might have a bug with start point and end_point which was fixed in 3.0.0 Hope that helps, Regina -----Original Message----- From: [EMAIL PROTECTED] on behalf of Bresnahan, Mike Sent: Mon 8/11/2008 1:02 PM To: postgis-users@postgis.refractions.net Subject: [postgis-users] PostGIS 1.3.3 on Windows XP Unstable -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I am trying to use PostGIS 1.3.3 with PostgreSQL 8.3 on Windows XP SP2 and I am having stability problems. The first problem I ran into is that calling buffer(the_geom,0) on an invalid geometry causes the server to crash with a blown assertion ("pts->size() > 1"). This problem was reported here: http://trac.osgeo.org/geos/ticket/187 The second problem I ran into is a crash when I call st_disjoint() on certain geometries. I have been unable to get any further information about this crash because the Visual Studio 2008 debugger refuses to attach to the crashing process with the message "Invalid security context". I tried running postgres.exe as a non-service under my own user ID, but I still received the same error. Is PostGIS 1.3.3 known to be very unstable on Windows XP? Might I have better luck on Linux? I don't have a Linux box available to me atm, so it would take some effort to test this question. -----BEGIN PGP SIGNATURE----- Version: PGP Universal 2.8.3 Charset: us-ascii wsBVAwUBSKBv9B6WPRoYuvd0AQjRHQf/YeFoMx+KXqAfLUmgc9W6gnAGGLcu6P9s NW1/ApatAFD/ezb/rT4Jz6BM3i+yowJk/sSW6y5TepQSWKN5qkQ/nfyqg2UtJoRn RJlrsnmmpsYsg5LyhGhJTWfry1BpVqSjWCGinTMKp0tmB0sDXgM7KTQ55jVIYU5q ctWcEK4RvpYd0yi1P2W5nIRBkBC60nMXsOS40y0BweM2D7JnGIA+qhwrgGubelQA xAqJkVJTF3qSWfngUKNuBfJKpwna8mIWmlRi9yEQ19iUxNy0SYSfcWOSOt+4O26S u6fWsY4zfxDhypzZ8wbR3j8NvOKMUD+24KUA1xr2HvrhwvmZm0Ag9w== =pPq1 -----END PGP SIGNATURE----- _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users ----------------------------------------- The substance of this message, including any attachments, may be confidential, legally privileged and/or exempt from disclosure pursuant to Massachusetts law.
