The code is strictly invalid with or without inlining, but with inlining the
compiler gets to see it. You are accessing buf via an lvalue which type
does not alias any of bufs members.
GCC 4.5 and up will tolerate this if you only ever read from the memory
location using an lvalue which type aliases the type of the lvalue you
used for the store.
