I noticed today that latex gets an fp exception on the following input
(derived from a much more interesting document, of course):

\documentstyle{article}
\begin{document}
Troff!
\filbreak
\eject
\end{document}

On an x86, the fault says:
  14097: math coprocessor	vlistout+0x49f	MOVBZX	0x5(AX),AX
which acid reports as:
  At pc:0x0001a9e6:vlistout+0x49f /sys/src/cmd/tex/web2c/tex/tex4.c:937
On a sparc the fault is reported as happening in the preceeding call to [z]round().

So, before I plunge into debugging this, has anyone already fixed it?
