Write a program which plays Russian Roulette!
If the program is started,
- there should be a 5 in 6 chance of it ending normally after printing "I survived!"
- there should be a 1 in 6 chance of the program crashing. (segmentation fault, etc.)
No input, and no other outputs are allowed.
The randomness must be fair: it must have a uniform probability distribution. This means an uninitialized variable (or a RNG without seed) MOD 6 will not be sufficient.
If the solution works with only one dedicated operating system / platform, you will receive a 6 byte penalty to the score.
Shortest code wins, not sooner than 10 days after first valid answer.
