I think that first character is missed here:

That's this line (738) in m_getfld():

    memcpy( buf, bp, c );

with bp off by one, I think due to this increment in Getc():

    if (read_more (s) == 0) {
        /* Pretend that we read a character.  That's what stdio does. */
        return EOF;

In spite of the comment, I don't know why readpos needs to be incremented.
