Following up my own posting.
It turns out that the problem seems to be related to the compiler.  When
I run the non-optimized version of paranoia on RTEMS it completes and
reports a single DEFECT (just like on Linux).  Interestingly enough,
when I run the optimized (-O4) version on Linux it locks up in exactly
the same place as does the optimized version on RTEMS.
