Now, a compiler that does not know that `val` can change will most likely implement that `switch` using a jump table with five entries.
Then, a `val` outside the [0..4] range will cause a jump to an address that could be anywhere in the program, and execution would proceed there.
Then, a `val` outside the `[0..4]` range will cause a jump to an address that could be anywhere in the program, and execution would proceed there.
Really, "all bets are off" if you get a data race.
Actually, it can be worse still: by looking at the generated code you may be able to determine where the stray jump will go for a given value;
this can be a security risk.
