I have not had any success limiting the scope of the source required for
an executable example. The code in question comes from the
self-validation code for the open-source Crypto++ library, a C++ class
library of cryptographic primitives, version 4.2. Let me know what would
be most useful for you at this point.

One additional note, it appears that removing "-fno-strict-aliasing"
from the compiler command line also makes the problem go away even with
-O2 or -O3. I doubt this is safe, however.
