Freecad crashes when attempting to draw a bezier curve in the Draft workbench or using the Involute Gear in the Part Design workbench. The specific error is this in both cases: *** Abort *** an exception was raised, but no catch was found. ... The exception is:SIGSEGV 'segmentation violation' detected. Address 0
Which version of freecad? Could you please attach emerge --info? Are you able to get a backtrace at all?
Created attachment 504892 [details] emerge --info
I tried both 0.16.6712 and 0.17_pre with the same error. The emerge info is attached. I have not yet been able to track down a more meaningful error message.
