Dear devs,
! error:  (nodes): attempt to double-free kern node 239, ignored
   !  ==> Fatal error occurred, no output PDF file produced!
MWE:
\catcode`@=11
\Umathordordspacing\displaystyle=\thinmuskip
   \Umathordordspacing\textstyle=\thinmuskip
\def\operator@font{\fam0}
\def\qopname#1#2#3{%
     \mathop{\mathpalette\@qopname{#1\kern\z@\operator@font#3}}\csname
n#2limits@\endcsname
   }
   \def\@qopname#1#2{%
     \hbox{$
       \Umathordordspacing\displaystyle=0mu
       \Umathordordspacing\textstyle=0mu
       \m@th#1#2
       $}}
\def\max{\qopname\relax m{max}}
   \def\min{\qopname\relax m{max}}
\catcode`@=12
$$\max a b / \min a b$$
\bye
ok, thank you . Checking it now.
It should be fixed in rev7518.
