| Summary | 0026400: Data Exchange, Step Import - Wrong step file crashes OC | ||||
| Description | Importing a STeP file with "REPRESENTATION_ITEM()" in it crashes the program. AFAICT REPRESENTATION_ITEM should have a NAME parameter, so the file is wrong. Still I think it could easily be imported (or at least gracefully rejected). What happens is that the following line (RWStepGeom_RWBSplineCurveWithKnotsAndRationalBSplineCurve.cxx:228): if (!data->CheckNbParams(num,1,ach,"representation_item")) return; finds an incorrect number of parameters and returns immediately. So ent->Init is not called; the entity is thus invalid, but still translated later. The crash happens in StepGeom_BSplineCurve::Degree() which is called on a null reference from StepToGeom_MakeBSplineCurve::Convert while handling the invalid entity. Maybe it would be possible to set aName to an emtpy string in RWStepGeom_RWBSplineCurveWithKnotsAndRationalBSplineCurve.cxx, when such a parameter is missing? | ||||

Current bug is not reproduced in the current master and doesn't reproduce in OpenCascade 6.8.0 After checking attached step file I didn't find any syntax or logical errors. All entities contain valid links to other entities. All OCCT releases from 6.8 to 7.6 don't throw any exceptions or crash |
