the implementation of protected operations must be implemented without locks.
Compilation fails if the compiler cannot generate lock-free code for the
The current conditions required to support this pragma are:

In addition, each protected subprogram body must satisfy:
- * May reference only one protected component
- * May not reference nonconstant entities outside the protected subprogram
- * May not contain address representation items, allocators, or quantified
