You should call DestroyFeature( poFeature ) within the loop. I just
looked at similar code of mine and I had also commented out
DestroyFeature, probably because of crashes. I tried removing it now and
there is no problem, I'm using the latest from CVS.

I don't see any reason for the crash. If you can reproduce the crash,
try adding some print statements or debug otherwise to see when the
crash happens. You could also try with the latest GDAL.
