[Gdal-dev] SetFeature crashing browser when used

There may be a bug in the implementation of the PHP_OGR wrapper that
frees the feature or does something illegal with it internally and that
causes the crash.
Can you please post a bug with a complete test case (complete script and
test dataset) in the GDAL bugzilla and make sure it is assigned to me?
I'm not sure when we'll be able to look into it due to other priorities,
but with a complete test case that will be easier.
