This was reported (for unspecified version/operating system) on stackexchange

http://tex.stackexchange.com/questions/330842/

but I see the same using 0.98.4 on cygwin64, and Enrico just confirmed
that the OSX build also segfaults.

Taking a file file.tex as

\documentclass{minimal}
\usepackage{lualatex-math}
\usepackage[partial=upright,nabla=upright]{unicode-math}
\usepackage{amsmath}
\setmathfont{XITS Math}

then

luatex --ini "&lualatex file.tex\dump"

produces a terminal output as listed below.



I don't think the dump would work as the user hoped (too much lua
state involved in the files) but it presumably shouldn't segfault.

While I was writing this, Enrico just confirmed the results with other fonts:

> On the other hand Latin Modern Math is good.
> Also STIX Math, but not Asana Math
> It seems a font specific problem
