Summary0031426: Modeling Algorithms - out of range within HLRBRep_PolyAlgo
DescriptionTest case hlr/poly_hlr/bug23625_1 crashes on regerenated triangulation with out of range exception. Probably range checks are missing within HLRBRep_PolyAlgo and it might be BRepMesh generating broken Poly_PolygonOnTriangulation.
Steps To Reproduce
test hlr poly_hlr bug23625_1 1
vclear
tclean a
incmesh a 7.6 12
vdisplay a
vcomputehlr a result -algoType polyAlgo


Result:
** Exception ** 000001D93DB39C30 : OSD_Exception_ACCESS_VIOLATION: ACCESS VIOLATION at address 0x000001D8551439B8 during 'READ' operation


Within debugger at line
