| Summary | 0000825: Loading a format that includes unicode-math and a loaded math font crashes luaTeX | ||||
| Description | LuaTeX segfaults when loading a format that includes unicode-math and a loaded math font. Removing the 3rd line of h.tex removes the crash but results in fontspec complaining that it cannot find latinmodern-math.otf, which exists. | ||||
| Steps To Reproduce | h.tex: \documentclass{article} \usepackage{unicode-math} \setmathfont{Latin Modern Math} d.tex: \begin{document} \end{document} luatex -ini '&lualatex h.tex\dump' luatex '&h d.tex' This is LuaTeX, Version beta-0.76.0-2013042316 (rev 4627) restricted \write18 enabled. Segmentation fault (core dumped) | ||||

Hello, This patch fixes this issue as well as other unreported ones. Thank you, -- Elie |
|

I can confirm that the patch fixes the segfault. It doesn't fix the issue of fontspec not finding any fonts after loading the format. (Is this even a LuaTeX bug, or is it in fontspec/luaotfload?) Thank you for your work. |
|
|
The issue with fontspec is not a LuaTeX bug, it's more on the fontspec, luaotfload and luatexbase side. It requires quite some work for it to be fixed, sadly I cannot promise I'll manage to get it done any time soon... |

the patch will be in 0.78; as mentioned in the comments, saving a math (or whatever) font is somewhat tricky when also lua resources are involved; it could be done (not a luatex engine issue btw, as there is no way it can know what to save, but in lua code) but it hardly makes sense to complicate matters too much |
