Hello there.

Yesterday I was trying to typeset a very, very long document (about 3000 pages in A4). Well, mkiv died with a

PANIC: unprotected error in call to Lua API (stack overflow (out of stack space))

It's easily reproducible with a simple

\starttext \dorecurse{50000}{ \input knuth }

Confirmed \starttext \dorecurse{50000}{ \input knuth }\stoptext die with

pages> flushing realpage 3987, userpage 3987 PANIC: unprotected error in call to Lua API (stack overflow (out of stack space))

its hard to figure out where it happens so probably taco has to run a variant with debugging on; maybe a core luatex function is not cleaning up the stack Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

i could run this \starttext \dorecurse{50000}{narf \page} \stoptext pdftex is ok luatex fails with pages > flushing realpage 3987, userpage 3987 PANIC: unprotected error in call to Lua API (stack overflow (out of stack space))

I think that is a bug, or not? yes, I think so.

That is mkii, right? (I am not interested in that)

Yes it was a bug, fixed in the luatex source repository now.

How high is the limit now? Just curious, since I saw LuaTeX building _a paragraph_ lasting few hundred pages without problems (on the other hand, pdfTeX couldn't do it). Regards, Vedran Miletić

And you'll get problems with pdfs with millions of objects (i.e. pages), as readers can't cope with them.

Which readers: do you refer to computer programs or to humans? (This is what Herbert Simon calls bounded rationality.) Alan

There is nothing hardcoded anywhere, but I suspect that after a few million pages some limit somewhere will be reached eventually: either the harddisk gets full, or your pdf reader will be unable to open the pdf due to its internal limits (luatex will happily create 10GB pdfs). Best wishes, Taco

I've done tests with tens of thousands of pages with mkiv with no problem so there must be something special going on now.
