Let me answer this first, as this question is easy: there is an
explicit tab character in the input file, here:

\def\splitComma#1{%
\directlua0{%
^^^^^^^^

Because the minimalistic format does not have plain's \catcode\^^I=10,
that ^^I gets category code 12, and so is typeset (in the \nullfont).

(Un)fortunately, I still get the correct output. But there are lots
of valgrind warnings while dumping the format, so I will investigate
those next. A bug during the format dumping seems most likely.

Wouldn't be the first one, either. Perhaps I should write a funding
proposal for ppc hardware.

Best wishes,
