Thank you very much.

I think it's a collectgarbage issue, or at least the gc has its role.

Just put collectgarbage('stop') on the top, and it should goes until the end.

If you have a TL 2015 with context, you can check that the plain format shipped with context is ok:

## build the luatex-plain.fmt

mtxrun --script plain --make

## run luatex --fmt=luatex-plain "test.tex"

mtxrun --script plain test.tex

(note that the context/plain format doesn't overwrite the canonical luatex.fmt format)

This is a bit strange, I'm still looking into it.
