Yes. > I'm using luatex 1.0.5 (rev 6307), but it crashes. I'm on windows and tried first with the luatex-dev that I had installed (1.0.4) and got a "luatex doesn't work anymore" window and then downloaded the newest luatex-dev from w32tex.org and with it it works. The credits doesn't show the revision but the version is 1.0.5. I tried also with the texlua from context (but imho they are on windows identical to the w32tex-version anyway). In all cases I had a small font.lua-file with your oneliner and called "texlua font.lua". The font is in the current folder. In miktex (1.0.0) I didn't get a crash, but I'm not sure if this really means that there is no error.
