--- Comment #44 from Rich Felker <bugdal at aerifal dot cx> --- Uhg. I don't know what kind of retroactive fix for that is possible, if any, but going forward this kind of thing (assumptions that impose ABI boundaries) should not be inlined by the template. It should just expand to an external call so that the implementation details can be kept as implementation details and changed as needed.
