[Comment 1 James Le Cuirot 2016-12-15 21:16:23 UTC]

Are you sure? It works fine here. I even rebuilt curl with adns, rebuilt lgogdownloader, and then rebuilt curl without adns, and it still didn't fail.

[Comment 2 Kris Scott 2016-12-15 23:20:08 UTC]

Created attachment 456344 [details]
Log file of with and without curl[adns]

Here's a log of me running with and without adns.

I think I'm having the same issue referenced here: http://stackoverflow.com/questions/9191668/error-longjmp-causes-uninitialized-stack-frame

[Comment 3 Kris Scott 2016-12-16 10:50:31 UTC]

I think I know why I'm getting this crash and you aren't. I have dlc in my library but do not have the associated game, I think this is causing some sort of error in lgogdownloader that crashes if async dns is not enabled. I'm going to report it upstream.

[Comment 4 James Le Cuirot 2017-01-24 22:19:51 UTC]

Please retry with 3.1 now that I've added it. It mentions libcurl thread-safety fixes.

[Comment 5 James Le Cuirot 2018-09-28 18:38:39 UTC]

Going to assume this is fixed now.
