BUG Report, filename of \input in pool

[Hans Ginzel]

	Dear TeX experts,

   I would like to submit a bug. TeX stores the filename of the \input
command in the pool. The string is not dealocated after end of input.
By next \input the_same_name, the string is put in the pool once more.
So, in document with enough lines \def\parakm{...}\input template,
TeX runs out of pool_size or count of strings.

   I do not see any reason, why the filename should be stored in the pool,
when TeX ends input of that file. I thought, that same strings are
not put twice in the pool. Also this is not true.

   I was TeXing document like:

	\begingroup
	\def\param{data}
	....	% about twenty \def's
	\input template	% two side document
	\endgroup

   On file with 4000 calls \input template, TeX gives up with message
overflowing pool size or count of strings. I put a \dump before it and
looked what has been in the pool. It was full with string template.
I have looked to section 511 of tex.web and confirmed my hypothese.
I consider this as a bug.

   I tested this on emtex and miktex. As a side effect I realized, that
MiKTeX does not support \trasingstats=2. There were no problems with other
memory kinds.


	Best regards
