Declaring it volatile causes the compiler to optimise differently (being
more careful with the precision of temporaries, stores, etc.), altering the
value of frac_SpF, which I believe controls frame padding.

It loads a floating point value from memory into a floating point register.
The value in memory is presumably invalid, so the CPU traps when it loads
it.
