result of sample source by pdflatex

On FreeBSD, latex and pdflatex make wrong result for the following LaTeX
source:

----- From here -----
\documentclass{article}
\newsavebox{\myboxi}
\newsavebox{\myboxii}
\begin{document}
\savebox{\myboxi}{\mbox{$I = \int_0^1 x^3dx$}}
\savebox{\myboxii}{\mbox{$c = \sqrt{a^2+b^2}$}}
\begin{quote}
  \usebox{\myboxi}\usebox{\myboxii}
\end{quote}

\begin{quote}
  $I = \int_0^1 x^3dx$, $c = \sqrt{a^2+b^2}$
\end{quote}
\end{document}
----- To here -----

In first quote environment, some symbols in math appear at incorrect positions. 
Second quote environment is treated correctly (see attach pdf file which is the
result of pdflatex). latex and pdflatex may fail to treat savebox/usebox.
But, this problem may not appear on other OS (Windows, etc). I think this may
be a bug of FreeBSD texlive's ports (I installed by ports).
Well, Japanese platex included in japanese/tex-ptex does not cause the problem
too. I don't know the reason why.

pdflatex version : pdfTeX 3.14159265-2.6-1.40.16 (Web2C 2015)
platex version : e-pTeX 3.14159265-p3.6-141210-2.6 (euc) (Web2C 2015)
FreeBSD version : FreeBSD 12.0-RELEASE-p11
