  Fixed bug 4097 - Segmentation fault by SDL_CreateThreadWithStackSize
  
  Dongsun Kim
  
  Normal case
  1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
  2. [thread 1] If successful, it calls SDL_SemWait.
  3. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
  4. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.
  
  Crash case (Segmentation fault)
  1. [thread 1] SDL_CreateThreadWithStackSize calls SDL_SYS_CreateThread.
  2. [thread 1] If successful, it calls SDL_SemWait.
  --> Error return due to SIGNAL(SYSTEM or Real Time) at sem_wait(pthread).
  3. [thread 1] SDL_CreateThreadWithStackSize calls SDL_DestroySemaphore, SDL_free.
  4. [thread 2] SDL_RunThread calls SDL_SYS_SetupThread, SDL_ThreadID, SDL_SemPost.
  --> Segmentation fault at strlen or sem_post.
