Summary	0033534: Modeling Alghorithms - BRepExtrema_ExtCC crash with Iges files [Regression]
Description	In OCC 7.7.1 and 7.7.2 upgrades, I encountered a crash in BRepExtrema_ExtCC. In OCC 7.6.0 BRepExtrema_ExtCC worked with no issue for the same two edges. In OCC 7.7.1 and 7.7.2 upgrades, is there any alternative api for BRepExtrema_ExtCC or is there a way to avoid this issue ? Here I have attached the IGES files of the two edges and a screenshot of the crash. I do appreciate any feedback you can share on this.
