It means I don't understand how it could happen.  The function
face_for_char (defined in fontset.c) explicitly tries the current
default font for any punctuation and symbol character, before it
starts looking in other fonts.  I don't understand why this fails for
you, and only in certain font sizes on top of that.  Perhaps you could
step through that code with a debugger and see what happens there?
