I got the same problem on Solaris 10 on SPARC with libgcrypt 1.4.1:
my$ ./basic --debug
Starting Cipher checks.
checking BLOWFISH [4]
checking DES [302]
checking 3DES [2]
checking CAST5 [3]
checking AES [7]
Bus Error
my$

I don't have time to debug further right now though.
Libgcrypt 1.2.4 works fine. Some alignment-forcing code appear to have
been removed between those two version. Another idea is that the
padlock could changed the alignment of some variable.
