The behaviour seems to depend on the compiler...
- With ObjectAda 7.2.2 SE I always get, in debug or release mode:
A:  62
B:  62
- With GNAT GPL 2006 I usually get the same, but also sometimes
A:  62
B:  57
or even down to
A:  60
B:  49
Here my competencies stop, I'm not a specialist in tasks & Co.
Then, is it your compiler or something missing in the code - I cannot decide...
