            Bug ID: 3392649
           Summary: ndisasm should read stdin in binary mode in stead of
                    text mode
           Product: NASM
           Version: 2.14.xx
          Hardware: All
                OS: All
            Status: OPEN
          Severity: normal
          Priority: Medium
         Component: Disassembler
          Assignee: nobody at nasm.us

     Obtained from: Binary from nasm.us

When reading from stdin, ndisasm doesn't put stdin in binary mode, but leaves
it in text mode.

Fix:

    } else {
#ifdef _WIN32
        _setmode(_fileno(stdin), _O_BINARY);
#else
        freopen(NULL, "rb", stdin);
#endif
        fp = stdin;
    }
