After that I tried `make -k' for four times and I got to get no
such error.  Though it must not be a right solution, the built
one works so far.  In the early three `make -k', the error
happened when byte-compiling an *.el file, but each time an *.el
file causing the error varied.  So, this isn't due to a Lisp code,
I guess.  For instance, one happened when compiling nntp.el, but
I can build Ma Gnus (from the Git master) without causing such
an error using this Emacs.  Anyway I will report it again if I
have a chance to get a C backtrace or other.
