>POSIX says:
Yes, this is ⓐ new in POSIX and ⓑ POSIX being stupid.
I consider this feature dangerous, and have asked for
it to be optional, in POSIX.
Until then:
$ mksh -o posix -c 'echo $((0777))'
511
When invoked as sh or -sh on Debian, mksh automatically
enables this mode. So, closing as “not a bug”.
