how to tell when have unaligned exception?

[Richard Coleman]

I'm testing some code of mine on FreeBSD-current/sparc64.  Is there any 
way for me to tell when code of mine hits an unaligned access?  Is there 
a way to have gdb break on such a trap when running as root?

I'm sorry if this is elementary.  Coming from the Intel world, I never 
had to think about this until now.
