This issue is now fixed. The GnuTLS library could not initialize in FIPS mode
since the self test failed. I have updated the self test now to use an ACVP
test that I just successfully verified yesterday.

I took an ACVP test vector that contains the verification of personalization
string and additional information to cover more code paths. Yet I removed the
number of self tests from 3 to 1. If you think that more than one self test is
beneficial, I can easily add more self tests using other ACVP test vectors I
now have on file.

The crash though is interesting: when I use the GnuTLS library without the
updated self test in FIPS mode with my test harness, the library would simply
not initialize and my application stops. The test, however, crashes. It seems
that the test does not handle a failure in the initialization of GnuTLS
