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
