Ramiro, It is illegal to change the layer definition with CreateField() if you have pre-existing features of that layer. This is documented here : http://www.gdal.org/ogr/classOGRFeatureDefn.html#40e681d8464b42f1a1fac655f16ac3dd
There's no way to check if the feature is "valid". So, just don't do it ;-) Le Tuesday 27 April 2010 21:17:17 Ramiro Gonzalez, vous avez écrit : > My application uses OGR to edit ESRI Shapefiles. > > If I follow this steps: > > 1_ Create a feature(OGRFeature::CreateFeature) using the feature definition > from an existing layer(layerA) > 2_ Add a field (OGRLayer::CreateField) to layerA > 3_ Try to save the feature (OGRLayer::SetFeature) in layerA > > I receive a SIGSEGV from function OGRFeature::SetField.
