Console output of the game, from patcher screen (SWAP_EFFECT_FLIP) to debug
attempt

League of Legends (latest version at this date -post World Championship)
crashes at champion selection. Usually a few actions are possible before crash,
but it always happens after a few seconds of the display of champion selection
screen.

Also, but maybe not the same bug, a similar error occurs randomly (e.g.
sometimes when alt-tabbing).

No debug info available, cf log.
