Unfortunately 17.2-1 contains a bug which causes most attempts to read large core files to crash. This is (or will be) fixed in 17.2-2 once it is available. You can download 17.2-2 directly from https://koji.fedoraproject.org/koji/buildinfo?buildID=3034524 if you want to give it a try. If the GDB crash still reproduces with that version then do please reopen this ticket (or create a new one, whichever is easier for you). Apologies for the 17.2-1 regression.
