I don't know if it is related or not, but I'm having a similar problem
with glibc. See this code:

        int
        main(void)
        {
                getchar();
                getchar();
                return 0;
        }

If the user writes a ctrl-d in the first getchar, then the second
getchar blocks until the user writes something else, although the
file already reached the end of file. I have tested it in NetBSD
to, and the second getchar returns automatically with EOF. I
don't know what is said in the C standard, but I think this is an
error in glibc.
