detach fails because the static_cast done above is invalid: It expects a Polygon, but it gets a Point (or rather garbage). This in turn happens because pack() of the Placemark is not called correctly during save: Only pack() of GeoDataFeature is called, not pack() of GeodataPlacemark() for some reason. Therefore too little data is written to the stream, which results in garbage being read later. Needs to be tracked down further. |
Version: (using Devel) Installed from: Compiled sources The KMLTest ( marble_build_dir/tests/KMLTest ) is currently failing because of a segfault in the GeoDataGeometry::detach method. I'm including the backtrace inline: Program received signal SIGSEGV, Segmentation fault.
