If I patch \sidefloatoutput (page-sid.tex) like so:

\def\sidefloatoutput
{\iffloatshort
\unvbox\normalpagebox
\setbox\floatbottom\lastbox
\ifdim\wd\floatbottom>\sidefloathsize
\penalty-201
\box\floatbottom
\else
\ifvoid\floatbottom
\else
\restoreleftindent
\ifdim\wd\floatbottom<\sidefloathsize
\parskip\zeropoint
%\noindent

it runs without error. It looks like the side float output routine
is called in the middle of this math display:

\startformula
a-b+c-d+f-g+h-e\equiv1\ (\mod 3),
\stopformula
which shows that all vertices cannot be made multiples of~3
simultaneously.

I think my patch somewhat odd, but at least it does not crash and I fear
that the sidefloat output in this case (a float next to a display that
forces a page break) is somewhat undefined anyway.

Best wishes,
Taco
