Dan Gohman (Mar 12 2020 at 18:20): Dan Gohman (Mar 12 2020 at 18:20):Is it a bug in rust that it lets me call eprintln in the drop of a thread_local object, but it crashes at runtime?

Alex Crichton (Mar 12 2020 at 18:23):@Dan Gohman its definitely dubious yeah, although not necessarily a bug
Alex Crichton (Mar 12 2020 at 18:24):Dtors in tls run in an extremely limited context
Alex Crichton (Mar 12 2020 at 18:24):But we probably should panic in linstd
Alex Crichton (Mar 12 2020 at 18:31):hm no this is definitely a bug
Alex Crichton (Mar 12 2020 at 18:31):I'll dig in
Dan Gohman (Mar 12 2020 at 18:40):It looks like it definitely is the eprintln, which I was only using for debugging, so I have a workaround, which is to not use eprintln :-}
