Unexpected interpreter crash

[Eclips4]

Originally taken from 104057
Minimal reproducible example:

import os


def make_bad_fd():
    file = open("test_file.txt", "wb")
    try:
        return file.fileno()
    finally:
        file.close()



fd = make_bad_fd()
os.write(fd, b"foo")

Error:

"Debug assertion Failed."
File minkernel/ctrs/ucrt/src/appcrt/lowio/write.cpp line 50, expression (_osfile(fh) & FOPEN)

Reproducible only on Windows and debug build of interpreter.
Is it a bug?

It's not a bug. See my comment on issue #104057.
