Hello, I get a crash in range-diff. It used to work in the past but I don't use it often so can't really say if this is a regression or a particular data triggering the crash.
It is not 100% broken - it woks on some other ranges. Thanks Michal Script started on 2019-09-23 12:15:54+0200 [0;32m✔[0;0m [0;33m~/kernel-source[0;0m [[0;35mSLE15-SP2[0;0m ↑·82[0;0m|[0;36m…17791[0;0m[1;34m⚑ 9[0;0m[0;0m] [0;37m12:15[0;0m $ gdb --args git range-diff 76ac02e3549..cd5f86d59a73 76ac02e3549..3b77e5866178 GNU gdb (GDB; openSUSE Leap 15.0) 8.2 Copyright (C) 2018 Free Software Foundation, Inc.
