[R-sig-Geo] Bug in writeOGR MSSQLSpatial driver?

Hi All,

Trying to run a well used script over the last few days has shown up an
error when writing a SpatialPolygonDataFrame to SQL SERVER using writeOGR.
This script worked 4 weeks ago, so I assume it is do with updates in the
latest version of rgdal.

The write attempt creates a new table in SQL SERVER, inserts a single row,
then exits with the following error.

> writeOGR(polyunion90df, dsn=dsn, layer=lyrout90, driver="MSSQLSpatial",
> layer_options=c("SRID=28355"))
Error in writeOGR(polyunion90df, dsn = dsnAbTrack_Analysis_SBY, layer =
lyrout90,  : 
  Failed to create feature

The single feature written to SQL Server appears normal, except the ogr_fid
field contains the following value "-2147483648".

The write attempt seems to update the geometry_column table successfully.

Using writeOGR with the ESRI shapefile driver successfully writes the SPDF
to a shapefile, which imports normally to a GIS.

writeOGR works normally if I run R 2.15.3 with rgdal 0.8-6.

quizzing the SQL SERVER spatial feature returns the following

ogrInfo returns the following
