<pre>Please read the generated assembly code. It's an empty label(LBB1_1) with a
jump to itself.
I can use global variables in this way if I don't care about race conditions.
The condition can be missed few times in the loop but eventually x will become
29 and the loop must exit. However, this is beyond the scope of this bug.</pre>
