[luatex] luaotfload | Updating the font names database:.../2010/texmf-dist/tex/luatex/lualibs/lualibs-file.lua:75: stack overflow

[Peter Dyballa]

Hello!

After an update mkluatexfontdb now works as advertised. It stops here:

	luaotfload | loading font: /Library/Fonts/Extrafonts/ 
mingliub.ttcSegmentation fault (core dumped)

What is the right place for the personal blacklist file? Neither  
documentation nor kpsewhich give a hint.


Here on Mac OS X 10.5.8 (Leopard, without Snow), PPC, mkluatexfontdb  
also reports:

	luaotfload | error: failed to open /Library/Fonts/NISC18030.ttf
	luaotfload | failed to load .Keyboard.ttf
	luaotfload | failed to load .LastResort.ttf

So these names should be put into the system's blacklist file as well.


The script seems to catalogue some font files more often than once:

	luaotfload | loading font: /Library/Fonts/Extrafonts/Vera.ttf
	luaotfload | loading font: /Library/Fonts/Extrafonts/Vera.ttf
	luaotfload | loading font: /Library/Fonts/Extrafonts/Vera.ttf
	luaotfload | loading font: /Library/Fonts/Extrafonts/Vera.ttf
	luaotfload | loading font: /Library/Fonts/Extrafonts/Vera.ttf

Is this necessary?


Mkluatexfontdb has a systematic flaw: It makes no difference between  
activated and not activated "installed" fonts (installed = can be  
found on disk). So different versions of the same font are scanned and  
catalogued. Is it chance which lets LuaTeX choose the font it uses for  
PDF output?
