| Summary | 0033417: Modeling Algorithms - Crash on BRepLib_ToolTriangulatedShape::ComputeNormals when deleting Poly_Connect | ||||
| Description | Using release binaries of occt-7.7.1, using BRepLib_ToolTriangulatedShape::ComputeNormals leads to a heap failure. is_block_type_valid(header->_block_use). Precisely at NCollection_Array1.hxx:431: //! Destructor - releases the memory ~NCollection_Array1 (void) { if (myDeletable) delete [] &(myData[myLowerBound]); } | ||||
| Steps To Reproduce | On a particular CAD (not all), mesh with Watson, then for every face, BRepLib_ToolTriangulatedShape::ComputeNormals(face, triangulation); | ||||
| Additional information and documentation updates | Stacktrace: ucrtbased.dll!00007ffc018bcbec() (Unknown Source:0) ucrtbased.dll!00007ffc018c0335() (Unknown Source:0) v.exe!operator delete(void * block) Line 38 (d:\a\_work\1\s\src\vctools\crt\vcstartup\src\heap\delete_scalar.cpp:38) v.exe!operator delete[](void * block) Line 32 (d:\a\_work\1\s\src\vctools\crt\vcstartup\src\heap\delete_array.cpp:32) v.exe!NCollection_Array1<int>::~NCollection_Array1<int>() Line 431 (include\opencascade\NCollection_Array1.hxx:431) v.exe!Poly_Connect::~Poly_Connect() (Unknown Source:0) v.exe!BRepLib_ToolTriangulatedShape::ComputeNormals(const TopoDS_Face & theFace, const opencascade::handle<Poly_Triangulation> & theTris) Line 37 (include\opencascade\BRepLib_ToolTriangulatedShape.hxx:37) | ||||
