| Summary | 0024919: ShapeFix can crash time-to-time due to inproper interator handling inside of Approx_SameParameter::Build function | ||||
| Description | Lines 461-464 of Approx_SameParameter::Build function: while(Param_de_decoupeC1(inter) <= fcons + deltamin) inter++; while(Param_de_decoupeC1(NbInt) >= lcons - deltamin) NbInt--; while(inter <= NbInt || ii < NCONTROL) { Variable inter isn't checked to be inside of Param_de_decoupeC1 range, what can result in access violation exception. | ||||
| Steps To Reproduce | I can't provide the model, which contains the case, when ShapeFix crashes due to this error. | ||||
| Tags | No tags attached. | ||||

@drazmyslovich: can you extract single edge or face on which the problem appears, instead of sending the whole model (which is confidential as far as I understand)? I deem single edge would not be confidential but still can allow creating a test case, and perhaps we can do more in-depth analysis of the problem. |

Unfortunately, I was unable to find the test case, where I've met this error. Sorry. |
