Hi Hans,

I think I might have found the source of the bug...

So ctxdata is not there ('a nil value')... if you look at line 563, you see
(this line is not indented like the others):

    563 ctxdata.flags.inputfile = filename -- is this right

Two observations:
* I think the answer to the comment is "no" :-D
* just a bit further up, lines 526-531, there is code that explicitly asks
whether ctxdata is there...

    526     if ctxdata then
    527         -- todo: interface
    528         for k,v in pairs(ctxdata.flags) do
    529             environment.setargument(k,v)
    530         end
    531     end

I don't know lua, but it seems that ctxdata being absent is possible, and
the problem could be fixed by account for the case that ctxdata is not
set...  what do you think?
