 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.
