Everything was working fine, when my game started crashing as follows (without recompiling):
Failed to initialize inotify, joystick connections and disconnections won't be notified
*** buffer overflow detected ***: /home/michal/zagadka/zagadka terminated

Apparently joystick (which I'm not using) was not initialized correctly, but something tried to use it anyway. This is the line that fails (Linux/JoystickImpl.cpp):
114: if (canRead(notifyFd)) // notifyFd is negative here
It would be great to be able to turn this functionality off altogether, so people don't get bogus crashes when playing my game.
