LaTeX/XeLaTeX Table of Contents: Page Numbers of by TOC Length

[patrickbucher]

I have a large PDF document (60 pages) generated from Markdown using XeLaTeX.

• Makefile
• Output
• Directory (all the other content)

All the numbers in the table of contents are off (too small) by two pages, and two pages is the length the table of contents needs.
In LaTeX, an additional run usually fixes that issue. How can this be achieved as a workaround? And is this a bug or am I doing something wrong?

EDIT: I'm using Pandoc Versoin 2.2.1

Pandoc should run the pdf-engine twice for TOC generation, but maybe there's a bug when using xelatex..? Can you try with the latest pandoc release? And can you try with pdflatex instead? Also, does it work when you do -o foo.tex, then run xelatex foo.tex once or twice?

[patrickbucher]

I just created an example to reproduce the bug (Pandoc version 2.2.1).
It works with --pdf-engine=pdflatex but fails with --pdf-engine=xelatex. With --pdf-engine=xelatex I can create a .tex file, and out of that a correct PDF with xelatex (standalone). Both pdflatex and xelatex need three runs for a correct TOC.

Alternative minimal repro:

perl -E 'say "\n\n# foo\n\n lorem ipsum " x 30' | pandoc --pdf-engine=xelatex -o foo.pdf --toc --verbose

[mb21]

Actually, we run the engine 3 + 1 = 4 times.

But the first two times it (sometimes?) doesn't run properly with xelatex? Partial output with --verbose:

[makePDF] Run #1
This is XeTeX, Version 3.14159265-2.6-0.99998 (TeX Live 2017) (preloaded format=xelatex)

Anyone any idea what's going on? Or can repro on other systems? I'm on macOS.

This appears to be an unwelcome consequence of the fix for #4484.
When I reverted it, the ! End of file on the terminal... why? messages went away and the table of contents was correct.
I am going to revert the fix to #4484. If someone wants to show me how to bring it back again without causing this problem, I'll consider it.
