| Summary | 0030201: Modeling Algorithms - ChFi3d_Builder::PerformMoreThreeCorner segfault by using nullptr | ||||
| Description | BRep_Tool::CurveOnSurface on lines 2225 and 2235 can set curv2d1 or curv2d2 to null. These variables are then used without checking for the null value leading to a segfault. Throwing an exception in the following patch is a band aid that avoids the segfault, but does not resolve the desire for a fillet.

Any luck with getting this use of a null pointer resolved? |
|
|
The segfault has been resolved in version 7.6.0, but the geometry construction still fails. |
