            Bug ID: 37245
           Summary: [libcxx] [test] ostreambuf.iter.ops\failed.pass.cpp
                    asserts about UB
           Product: libc++
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: All Bugs

This test has the following assertion:

        std::ostreambuf_iterator<char> i(nullptr);
        assert(i.failed());

N4727 [ostreambuf.iter.cons]/3 says:

ostreambuf_iterator(streambuf_type* s) noexcept;

Requires: s shall not be a null pointer.

It seems this test is incorrect. I'm not sure if it should be outright deleted,
moved to the libcxx subdirectory, or something else.
