Comment(by robe):

 First fails on my:

 {{{
 PostgreSQL 9.3rc1, compiled by Visual C++ build 1600, 64-bit
 POSTGIS="2.1.2dev r12221" GEOS="3.4.2-CAPI-1.8.2 r3924" PROJ="Rel. 4.8.0,
 6 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.7.8"
 LIBJSON="UNKNOWN" RASTER
 }}}

 as well.  2nd also fails on my 64-bit consistently when running n psql and
 pgAdmin


 {{{
