Compiling the following MWE with the XeLaTex at MIPS leads to the error:

xdvipdfmx:fatal: Bad DVI: negative point_size: -1371074304

MWE:

\documentclass{article}
\XeTeXtracingfonts=1  % for verbose logs
\usepackage{fontspec}
\begin{document}
\title{Test}
\author{Foo}
\maketitle
Test content test content.
\end{document}

Minimal compilation command:

xelatex test

Verbose compilation command:

xelatex -recorder -output-driver='xdvipdfmx -vv >> test.fls 2>&1’ test

Failure is reproduced only at MIPS (which is big-endian), all other systems (such as amd64, i386 and even similar 32-bit big-endian hppa).
It is also reproduced at QEMU chroot and at MIPS build machine (it blocks the asn1c build by the way).
Failure is not reproduced using debian stable (texlive 2014).

Logs and output are provided by adding the

\XeTeXtracingfonts=1

to the tex file and by running xelatex and xdvipdfmx in a verbose mode using the command:

xelatex -recorder -output-driver='xdvipdfmx -vv >> test.fls 2>&1’ test

Files test.log and test.xdv are attached.

DVI Comment: XeTeX output 2016.09.03:0919

xdvipdfmx:fatal: Bad DVI: negative point_size: -1371074304

Output file removed.

It looks like xdv contains a value that is badly converted between different endianness.

An xdv file produced at amd64 box can be successfully converted to pdf at MIPS box using xdvipdfmx.
So I compared these test.xdv files:

% xxd test-amd64.xdv > test-amd64.xdv.xxd
% xxd test-mips.xdv > test-mips.xdv.xxd
% diff test-amd64.xdv.xxd test-mips.xdv.xxd

Differences between two xdv files are clearly in a byte order.
If I try to compile dvi files from a minimal LaTeX document then resulting DVI files are the same.

So it is a possible bug in XeTeX xdv generator.
