--- Comment #1 from Nicolai Hähnle nhaehnle@gmail.com --- Thanks for the report! Could you please provide a backtrace with debug symbols?
Also, could you please check whether the 17.3-branchpoint crashes, and depending on the result, use a `git bisect` to find the commit that either fixed this on master or broke it on 17.3.
