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 David This is LuaTeX, Version 0.98.4 (TeX Live 2017/dev) (INITEX) restricted system commands enabled. .... ending (load luc: /usr/local/texlive/2016/texmf-var/luatex-cache/generic/fonts/otl/xi ts-math.luc)(load luc: /usr/local/texlive/2016/texmf-var/luatex-cache/generic/f onts/otl/xits-mathbold.luc)) Beginning to dump on file file.fmt (format=file 2016.9.22) 23263 strings using 381023 bytes 894279 memory locations dumped; current usage is 280&434569 21646 multiletter control sequences \font\nullfont=nullfont \font\OMX/cmex/m/n/10=cmex10 \font\tenln=line10 \font\tenlnw=linew10 \font\tencirc=lcircle10 \font\tencircw=lcirclew10 \font\OT1/cmr/m/n/5=cmr5 \font\OT1/cmr/m/n/7=cmr7 \font\OT1/cmr/m/n/10=cmr10 \font\OML/cmm/m/it/5=cmmi5 \font\OML/cmm/m/it/7=cmmi7 \font\OML/cmm/m/it/10=cmmi10 \font\OMS/cmsy/m/n/5=cmsy5 \font\OMS/cmsy/m/n/7=cmsy7 \font\OMS/cmsy/m/n/10=cmsy10 \font\EU2/lmr/m/n/10=file:lmroman10-regular:script=latn;+trep;+tlig; \font\EU2/lmr/m/sl/10=file:lmromanslant10-regular:script=latn;+trep;+tlig; \font\EU2/lmr/m/it/10=file:lmroman10-italic:script=latn;+trep;+tlig; \font\EU2/lmr/bx/n/10=file:lmroman10-bold:script=latn;+trep;+tlig; \font\EU2/lmss/m/n/10=file:lmsans10-regular:script=latn;+trep;+tlig;Segmentation fault (core dumped)
