[tex-live] Error with LuaLaTeX after last update

[Karl Berry]

Hi Enrico,

        Could not undump 27303 1-byte item(s): <fd:3>: unexpected end of file.

The MacOSX binaries have not changed since the 2011 release, as usual.
All that changed was a small fix to the fmtutil script (ironically for
the sake of MacOSX; diff below).  So I suspect the problem would have
happened at any time formats were rebuilt.

It's not clear to me why the script update should have caused any
formats to be rebuilt.  I wasn't expecting that.

What the problem actually is, I don't know.  Maybe the hardware or OS
version changed between the time you installed TL and now?  Anyway,
if you run (from the shell)
fmtutil-sys --byfmt lualatex
it should hopefully tell you about log files to look in.
