Hello,

no.  There is -Wcast-align (disabled by default), but it does not
trigger in this case.  -Wpacked (also disabled by default) announces
that "packed attribute causes inefficient alignment for 'i'"
(but does not mention f; umm...).  And that's it, these are all warnings
that are triggered by STRICT_ALIGNMENT.
