Core dump on tab completion
trafficstars
I was just fooling around, then pressed tab on std: and got a core dump.
I should be running this cling rev: https://github.com/NixOS/nixpkgs/pull/64319/files#diff-fffc25cba23795f57def88838e588058R10 , which is old, so it may be fixed already.
I can reliably (at the moment at least) repro with
[cling]$ #import <iostream>
[cling]$ using namespace std;
[cling]$ cout << "hi";
[cling]$ std:<press tab here>
