White space in argument

Running tectonic 0.14.1 on https://github.com/sneakers-the-rat/dissertation gives

error: something bad happened inside BibTeX; its output follows:

===============================================================================

Almost definitely a result of my port, I'll look into it.

It's a syntax error in line 5196, the \citep command expects a single ending } but it's given two braces instead.

See: infrastructure_dissertation.tex#L5196 and infrastructure_dissertation.tex#L5196.

I don't think that's the issue -- the second } pairs to the preceding \sidenote{.

@vlasakm You're right, after more careful inspection that's not what the cause is.

Sorry for the delay - I'm busy currently, but I'll be trying to get to this soon. I suspect the issue is with my bibtex port (converting the legacy C code to Rust), and in that case it's likely due to an off-by-one error or a missed call in my changes that the tectonic-on-arxiv tests (which run tectonic, including the bundled bibtex, against a lot of arxiv documents) didn't cover. If that's the case, I'll make sure to add a regression test so it doesn't happen in the future.

Regarding the .bib files and your port, they compile using tectonic as well as LuaLaTeX / XeTeX, both producing 1080 references:

MWE test.tex

\documentclass{article}
  \usepackage{amsmath, amsfonts}
  \usepackage[style=numeric,citestyle=numeric,
    backref=true,sorting=none]{biblatex}
    \addbibresource{autopilot.bib}
    \addbibresource{infrastructure.bib}
    \addbibresource{speech_modeling.bib}
    \addbibresource{speech.bib}
  \usepackage{totcount}
    \newtotcounter{citenum}
    \AtEveryBibitem{\stepcounter{citenum}}

\begin{document}
  \nocite{*}
  \printbibliography[title=\bibname{} (\the\totvalue{citenum})]
\end{document}

Compile with

biblatex=$(kpsewhich biblatex.sty) biblatex_dir=${biblatex%/*}

tectonic -p test.tex -Z search-path="$biblatex_dir"

I think I found the root cause and will be opening a PR shortly - the actual issue was small, despite taking me several hours to track down. A test will be included to prevent regressions.
