Looking at fs/reiser4/debug.h suggest that this is something done on purpose
to guard against other problems.

Does only reiser4 produce the above warning?

yes, "duplicated case value" is a result of our compile-time assertion if it fails.

But the assertion is wrong because the assumtion that struct coord has no
implicit padding is wrong on alpha.

No. I get these from various parts of the kernel, but are a lot less
frequent now on 2.6.7 than on previous kernels.
