While working on our cocos2dx game we noticed that the game would occasionally crash when there were timeout errors. I finally decided to dig in look for a solution. Found out that curl apparently fails to send a timeout notification. The proper fix (as noted on the Curl site as well is to set the following curl option in code)
Thank you for this, I haven’t encountered this crash but when I look more into this I’ll be sure to include your solution in my game. Have you submitted an issue to the cocos2d-x team?
