[NTG-context] lua code prevents compilation

Dear list,

I have the following sample:


    function document.addfunnyhyphen(tfmdata)
        local underscore = utf.byte("_")
        local char       = tfmdata.characters[underscore]
        tfmdata.characters[0xFE000]   = {
            width    = 0,
            height   = 0,
            depth    = 0,
            commands = {
                { "right", -char.width },
                { "down", char.depth },
                { "slot", 1, underscore },



\def\CoverImageFont{\scale[width=\textwidth]{\ornamenta }}


For some reason unknown to me, the only way to compile the sample is to
remove the luacode snippet.

I need the lua code to have underscore hyphenation in type commands. And
I need two extra \definehyphenationfeatures and \sethyphenationfeatures
to invoke it.

Have I hit a bug or what am I missing?

Many thanks for your help,
