The file use is there (sorry it's big, I don't have access to ArcGIS now to isolate the issue): https://www.dropbox.com/s/ykow18oute35byv/25ez1.gdb.zip?dl=0 and the layer is “terreinVlak_3D_LOD0” If I do: ogr2ogr v1112 25ez1.gdb/ terreinVlak_3D_LOD0 then, as can be seen in that screenshot (this is only one example, that file contains 608 invalid triangles), the geometry with TOP10_ID=""107838021"" has corrupted triangles (these are multi but if you explode them you get triangles with inner rings) If I export the same GDB with ArcGIS, I do not get these: https://dl.dropboxusercontent.com/s/esq5ylinlztg087/2015-03-24%20at%2017.32.png?dl=0 I have GDAL v1.11.2 under Mac OS X from KyngChaos.
