| Summary | 0023343: Crash (ACCESS VIOLATION) in GeomPlate_BuildPlateSurface / MakeApprox if init Surface is set | ||||
| Description | If GeomPlate_BuildPlateSurface is used with an initial surface and a curve constraint, it is possible to get an ACCESS VIOLATION by an internal call of GeomPlate_MakeApprox. If the curve constraint can not be completely projected onto the surface. -------------------------------------------------------- GeomPlate_MakeApprox App(myGeomPlateSurface, myTol3d, 1, 3, 15*myTol3d, -1, GeomAbs_C0, 1.3); -------------------------------------------------------- Because the parameter "myGeomPlateSurface" is Null. This was found at Line 525-529 at file GeomPlate_BuildPlateSurface.cxx The Exaption will raised on Line 329 at file GeomPlate_MakeApprox.cxx, by getting the UV-bounds of the surface. -------------------------------------------------------- myPlate->RealBounds(U0, U1, V0, V1); -------------------------------------------------------- Perhaps the variable must be initialized as in line 1689 at file GeomPlate_BuildPlateSurface.cxx ? -------------------------------------------------------- myGeomPlateSurface = new GeomPlate_Surface( mySurfInit, myPlate ); -------------------------------------------------------- | ||||
| Steps To Reproduce | The Crash can reproduced with Draw (gplate). 1) unzip "gplateCrash.zip" 2) start the script "source gplateCrash" or copy & paste: restore initFace.brep initFace restore edge_constraint.brep edge_constraint point p1 30 -33.4729635533385 49.7661550602442 point p2 30 -49.6961550602442 33.3929635533386 point p3 23.3333333333333 -50 30.07 point p4 -30 -33.4729635533386 49.6161550602442 gplate r1 1 4 initFace edge_constraint1 0 p1 p2 p3 p4 | ||||
