There appears to be a bug [1] in gcc when using varargs with this attribute. Disable it for sandbox so that functions which use that can work correctly, such as install_multiple_protocol_interfaces().

See my patch instead please.
OK I see it now. Do you know what gcc fixes this problem?
The bug you found was really just a gcc bug that hit early gcc6 versions. I doubt you're running into it :).
OK, so in fact gcc does not support varargs problems with the ms_abi?
Gcc needs to know whether varargs are sysv varargs or ms varargs. And it differentiates between the two with different variable types for va_list.
