[GNC] Strange crash (macOS specific)

[R. Victor Klassen]

Thanks.  I’ll keep an eye out for it, and try that if it happens again.  I have Xcode and the command line tools installed on that machine, so if it happens, I can try that.

It was several weeks before instances so far.

Looking in the crash report it is failing to satisfy itself with the code signing and aborting.   I reinstall and the problem is resolved.  Or is it?  It recurred about two weeks later.
