I have to process a big number of files with the same preamble. Therefore I try to build a custom format file. The biggest »time eater« is font loading in lualatex, so I try to load the fonts in the format file.
I copied lualatex.ini and modified it slightly, so that it loads my preamble just before dumping:
% [...] % the next line is added by me \input mypreamble.tex % restore \dump for derived formats (mylatex, etc) that might use it \let\dump\DUMP \let\DUMP\undefined \dump
When I try to use the generated format file, I get an segfault:
> luatex \&mylualatex.fmt This is LuaTeX, Version beta-0.70.1-2011061416 (rev 4277) restricted \write18 enabled.  4569 segmentation fault luatex \&mylualatex.fmt
