Re: core dump while in gnus

    (gdb) p *current_buffer
    $7 = {
      size = 537002092, 
      next = 0x10765200, 
      own_text = {
        beg = 0x4060018 <Address 0x4060018 out of bounds>,

If this is what happens, I suggest you add code at the places
that set the beg field which will check whether the new
value is invalid.  That way, when it happens again, you will
catch it earlier and you might be able to learn more.
