iOS 11 is official supported by SDL2

Hello Folks,

Been using SDL just for threading and mutex in my networking code and having problems with iOS 11.
Same code is running fine with iOS 8,9,10. When I try to inspect the situation with iOS11 in my library’s bitcode, there is a overflow between threads.

Sometimes some variables would go NULL without anything saying like bad error or something. My code communicate through POSIX socket between SDL_threads.

POINT: is SDL2 [ Especially SDL_pthread ] on iOS 11 officially tested [ core guys tried out and thumbs up ] ?

Appreciate your library works everyday at work
