I guess, I could extract all members other than 'data' to a separate union and then:

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

This would require more modifications to the code though.

(Sigh... if only we could inherit unions...)

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.
