--- Comment #1 from Steven Schveighoffer ---
This is because in the first case, S has a hidden context pointer to the stack
frame of main().
If you mark it as a static struct, you will not have this problem.
Note that the ultimate reason it fails is because any items that have
indirections cannot be implicitly converted to immutable.
