[gdal-dev] Definite problem with XERCES 3.0.x and GDAL

I'm running 1.6.1 stable that I downloaded on 7/14 and xerces 3.0.1 on a
RHEL5.2 64 bit system.


When I convert a shapefile to GML and then try to convert back to
shapefile I was getting:


ERROR 1: <coordinates> element missing value


And an invalid shapefile with no polygons. I'd get this error at various
other points too.



I spent some time in gdb and found that a XERCES method parseNext inside
of the GMLReader::NextFeature() was returning an empty coordinates block
even though my GML had coordinates.


I backed out of xerces 3.0 to xerces 2.8 and recompiled GDAL and reran
my test and now everything is working.


I'm not sure what the next steps are here but xerces 3.0 and 3.0.1 did
not work with OGR.
