That semaphore code should work, and certainly shouldn't hang. Is there
any possible significance to the fact both your examples show task (3)
as the one that does a RELEASE but never gets to RELEASED? Are you
sure the program is hanging, and not crashing and somehow hanging
during the attempted crash?
Pragmas Atomic and Volatile should certainly not be necessary. The
whole point is that only one task at a time can execute the entries
or procedures in, and thus access or change the value of data
(Busy, in this case) of, a protected object.
