I don't get the error you describe (it builds fine) but I consistently
get the following error with any program that uses TripleDES.

dexter:~$ cipherSpeed tripledes
Exercising tripledes...

Failed self-test...

...which is bizarre, and the error changes depending upon the
optimization flags -- with -02 -march=athlon-mp, it fails at the same
point, but from a ClassCastException because the TripleDES.Context
object is (inexplicibly) an Integer.

This looks very much like a compiler error.
