I'm not particularly interested in it because of its RTEMS-ness.
Rather, I'm interested in it because it's a new case of the compiler
failing to correctly process valid code, not present in previous
versions of GCC. The test case is not RTEMS-specific; it's a problem
that looks like it could equally well apply to lots of other code out
there making use of volatile storage.
