Summary | 0026400: 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? | ||||||||||||
