A few. One was when I first fell through the floor in The Doom in Shadow the Hedgehog because I was going faster than the gamecube could load the floor. Another was in NetHack, when I put my cockatrice corpse in my bag of holding "to avoid mistakes" -- except I'd already taken my Gauntlets of Power off to cast some spells, meaning I touched the cockatrice corpse with my bare hands and turned to stone and died. >_<
Also, does the entirety of Metroid: Other M count, even though I got enough warning to never actually buy or play it?
