Hello,

I'm not sure it's useful to report it here, but just in case:

Following (plain TeX) example

\attribute0=-"7FFFFFFF\relax
\immediate\write-1{Anything}
\immediate\write-1{Anything}
\skip0=1pt plus 100pt\relax
\showthe\skip0
\bye

outputs

1.0pt plus 100.0pt minus 0.00002pt.

while

\skip0=1pt plus 100pt\relax
\showthe\skip0
\bye

outputs

1.0pt plus 100.0pt.

(reported here: http://tracker.luatex.org/view.php?id=923 , found

Thank you,
