[ruby-core:57813] ruby-2.0.0-p247siphash.c:443: bug report

Hello there,

I just ran the static analysis tool cppcheck over the source code
of ruby-2.0.0-p247

It said

[siphash.c:443] -> [siphash.c:445]: (warning) Variable 'last' is reassigned a value before the old one has been used. 'break;' missing?
[siphash.c:445] -> [siphash.c:447]: (warning) Variable 'last' is reassigned a value before the old one has been used. 'break;' missing?
[siphash.c:447] -> [siphash.c:460]: (warning) Variable 'last' is reassigned a value before the old one has been used. 'break;' missing?
[siphash.c:460] -> [siphash.c:462]: (warning) Variable 'last' is reassigned a value before the old one has been used. 'break;' missing?
[siphash.c:462] -> [siphash.c:464]: (warning) Variable 'last' is reassigned a value before the old one has been used. 'break;' missing?

Source code is

switch (len % sizeof(uint64_t)) {
case 7:
OR_BYTE(6);
case 6:
OR_BYTE(5);
case 5:
OR_BYTE(4);

Suggest add some break statements.

Regards
