Bug? about controling key whose length is 9

[thawk105]

I may found bugs. Could you read this comment?

masstree-beta/configure.ac

Line 446 in 4f4bc58

AC_DEFINE_UNQUOTED([HAVE_UNALIGNED_ACCESS], [1], [Define if unaligned accesses are OK.])

This line defines HAVE_UNALIGNED_ACCESS to 1.

Then, comparing method is forced this line.

masstree-beta/string_slice.hh

Line 151 in cef4cc4

#if HAVE_UNALIGNED_ACCESS

I think there is a problem.
If we use the key whose length is 9, or 17, or..., which isn't divisible by 8, it causes segv.

Is this right?
Sincerely yours,
