The hash implementation casts the input pointer to uint64_t* and directly reads from this, which may cause unaligned accesses. Use memcpy() instead so this code will not crash with SIGBUS on sparc. https://bugs.gentoo.org/show_bug.cgi?id=636400 (cherry picked from commit 1e2ec8a) Co-authored-by: Rolf Eike Beer <eike@sf-mail.de>
