Summary	0002333: Crash when attempting union or intersection
Description	Every time I attempt to create a union or intersection between two solid objects. Test file is attached.
Steps To Reproduce	1) Open the attached file "bugtrigger.fcstd" in FreeCAD. 2) Go to the Part workbench 3) Select both the GroundFloor and Opening objects in the Model tree on the left. 4) Click on either the "Make a union of several shapes" or "Make an intersection of two shapes" buttons. 5) FreeCAD crashes with the following error message on the terminal: * Abort * an exception was raised, but no catch was found. ... The exception is:SIGSEGV 'segmentation violation' detected. Address 0
Additional Information	If I start FreeCAD in GDB, it prints the following when it crashes: Program received signal SIGSEGV, Segmentation fault. 0x00007fff83d258fc in BOPAlgo_PaveFiller::MakeSplitEdges() () from /usr/lib/x86_64-linux-gnu/libTKBO.so.8 Running the GDB command "bt" gives the following output: #0 0x00007fff83d7c8fc in BOPAlgo_PaveFiller::MakeSplitEdges() () from /usr/lib/x86_64-linux-gnu/libTKBO.so.8 #1 0x00007fff83d9efb5 in BOPAlgo_PaveFiller::Perform() () from /usr/lib/x86_64-linux-gnu/libTKBO.so.8 0000002 0x00007fff83d39691 in BRepAlgoAPI_BooleanOperation::Build() () from /usr/lib/x86_64-linux-gnu/libTKBO.so.8 0000003 0x00007fff83d33db9 in BRepAlgoAPI_Fuse::BRepAlgoAPI_Fuse(TopoDS_Shape const&, TopoDS_Shape const&) () from /usr/lib/x86_64-linux-gnu/libTKBO.so.8 0000004 0x00007fff876fbee2 in Part::MultiFuse::execute() () from /usr/lib/freecad/lib/Part.so 0000005 0x00007ffff6f9f6e2 in App::DocumentObject::recompute() () from /usr/lib/freecad/lib/libFreeCADApp.so 0000006 0x00007fff8771d021 in Part::Feature::recompute() () from /usr/lib/freecad/lib/Part.so 0000007 0x00007ffff6f76a49 in App::Document::_recomputeFeature(App::DocumentObject) () from /usr/lib/freecad/lib/libFreeCADApp.so 0000008 0x00007ffff6f7b505 in App::Document::recompute() () from /usr/lib/freecad/lib/libFreeCADApp.so 0000009 0x00007ffff6fb785b in App::DocumentPy::recompute(_object) () from /usr/lib/freecad/lib/libFreeCADApp.so 0000010 0x00007ffff6fb78a3 in App::DocumentPy::staticCallback_recompute(_object, _object) () from /usr/lib/freecad/lib/libFreeCADApp.so 0000011 0x00007ffff66d97dc in PyEval_EvalFrameEx () from /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 0000012 0x00007ffff681b73c in PyEval_EvalCodeEx () from /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 0000013 0x00007ffff66d2e09 in PyEval_EvalCode () from /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 0000014 0x00007ffff676c096 in PyRun_StringFlags () from /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 0000015 0x00007ffff6c333b6 in Base::InterpreterSingleton::runString[abi:cxx11](char const) () from /usr/lib/freecad/lib/libFreeCADBase.so 0000016 0x00007ffff754b825 in Gui::Command::doCommand(Gui::Command::DoCmd_Type, char const, ...)

torquil 2015-11-08 22:10 reporter ~0006536	It seems that this is a problem with the particular version of OpenCASCADE currently in Debian Sid, and the problem has been reported in Debian bug report #802517: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=802517 So this can probably be closed.
