Description
This is described in: http://postgis.refractions.net/pipermail/postgis-users/2011-July/030413.html
when converting data from: http://spatialreference.org/ref/iau2000/49900/
To: http://spatialreference.org/ref/iau2000/49910/
I have confirmed this to be an issue on Windows (my platform is Windows 7, 64-bit running PostGIS 2.0 32-bit on 9.1 beta 3).
"POSTGIS="2.0.0SVN" GEOS="3.3.1dev-CAPI-1.7.1" PROJ="Rel. 4.6.1, 21 August 2008" LIBXML="2.7.8" USE_STATS"
and shows in logs
LOG: server process (PID 2608) was terminated by exception 0xC0000005
The person who posted this is running 8.4 on windows XP with the below but had also tried it with PostGIS 1.5 (same proj)
"POSTGIS="2.0.0SVN" GEOS="3.3.1dev-CAPI-1.7.1" PROJ="Rel. 4.6.1, 21 August 2008" LIBXML="2.7.8" USE_STATS"
This could be just an issue with windows or the older proj we compile our windows binaries with.
Our next try will be to recompile using proj 4.7 to see if we exhibit the same error and if not just bite the bullet and switch PostGIS 2.0 to use 4.7 for windows builds. Which we were planning to do anyway after some more testing.
Duh I should have looked at the spatial_ref_sys isnert statement generated, the 49910 is missing a proj4text string, so of course PostGIS could never transform this. Though I suppose it still shouldn't crash and we shouldn't allow inserts into spatial_ref_sys with no proj4text. That's a separate topic though.
