Dear devs,
The example below crashes LuaTeX with a segmentation fault.  It is
    reproducible
    with LuaTeX 1.10.1 7143 and LuaTeX 1.11.2 7226.  To this end I built
    7226 from
    source with --debugopt to get a backtrace, which can be found below
    as well.
Cheers, Henri

\directlua{token.set_macro(-1, "foo","\string\\,")}
    \show\foo
    \foo
    \bye
I guess that we have to check if catcodetable -1 is already defined...
i already sent you a patch, probbaly also ok for trunk

but one needs to be careful as fo rinstance \string\foo is seen as 
<formfeed>oo so often one also needs to escape properly
