* apt-pkg/contrib/sha1.cc:
- fix illegally casts of on-stack buffer to a type requiring more alignment than it has resulting in segfaults on sparc (Closes: #634696) The problem is how sha1.cc codes the SHA1 transform, it illegally casts the on-stack workspace buffer to a type requiring more alignment than 'workspace' is actually declared to have. This only shows up recently because gcc-4.6 now does a really aggressive optimization where it gets rid of the workspace buffer entirely and just accesses 'buffer' directly, and assumes it has the necessary alignment for 32-bit loads (which it doesn't).
