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

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.
