[FWTools] GDAL OGRSpatialReference::Validate()

Dear all,

I'm having a bit trouble using the method OGRSpatialReference::Validate().

When I define a projection Mercator

PROJCS["World_Mercator",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["W
GS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.01745
3292519943295]],PROJECTION["Mercator"],PARAMETER["False_Easting",0],PARAMETE
R["False_Northing",0],PARAMETER["Central_Meridian",0],PARAMETER["Standard_Pa
rallel_1",0],UNIT["Meter",1]]

as it is the exact definition of ESRI, the validate method fails with the
error code "OGR_CORRUPT_DATA".

I use the following steps:

1. create a new new OGRSpatialReference myRef
2. call myRef.importFromWkt() with the string above as argument
3. call myRef.morphFromESRI()
4. call myRef.Validate() returning OGR_CORRUPT_DATA

Do you have any idea what's going wrong?

The definition string is taken from ESRI ArcGIS 9.0

Thanks for any help

	Martin
