Description bryan ogawa 2006-05-17 18:05:13 UTC 
In NPTL, sem_wait() can return EINTR . The current SDL_SemWait() will return the EINTR (which might be OK), but code which depends on SDL_SemWait (e.g. in SDL_CreateThread) does not check for EINTR.

this can cause a race in SDL_CreateThread().

note that SDL_SemWait() documentation doesn't note that it can return EINTR if you choose to have SDL_SemWait continue to return EINTR.

actually, this shows up on Linux, not mac.
Comment 2 Ryan C. Gordon 2006-05-17 19:43:00 UTC 
Fixed in svn revision #2476.
