Could you do this with an anonymous union? eg:

union function_buffer
     mutable union function_buffer_members
     mutable char data[sizeof(function_buffer_members)];

Haven't tested this; not sure if it's legal to get the sizeof a subtype
nested in the same scope like this, but it at least seems plausible.
