Actually it will break whenever the compiler does not do constant
propagation and dead code elimination.
This happens generally for all the lowest optimization level (-O0).
It is not relevant since loads of code already assumes this.
Some people complain about this for debugging, though personally
I think that at -O0 the assembly code is completely unreadable
and you are limited to quite high-level debugging whereas -O1 usually
works just fine even for using a somewhat dumb debugger like gdb while
having mostly readable assembler code (as far as such exists).
