We had to install the most recent pandoc release as the old failed for
the recent texlive release with rmarkdown.
Apparently pandoc gives a different error message for empty titles now.
The simplest solution would be to provide a proper title anyway.

Maybe already obvious to you, but this seems to be coming from pandoc,
not from R machinery. There are a few extra lines in the log that seem
to be relevant ...

pandoc: Stack space overflow: current size 33624 bytes.

I think you'd have to figure out what's happened to the pandoc
version/configuration in the most recent Debian setup on CRAN ... I
don't know if there's a canonical place (or anywhere, for that matter)
where one can find a complete list of library/tool versions for the
various platforms on CRAN ...

HI all,
Submission of a new version of the tidyhydat package to CRAN, I get
this warning on the pre-test checks for Debian:
* checking top-level files ... WARNING
Conversion of ‘README.md’ failed:

Here is the actual log:
https://win-builder.r-project.org/incoming_pretest/tidyhydat_0.5.0_20191127_215625/Debian/00check.log
The .yaml header for the README has not changed since the last
successful submission. Looking at the changes to R 3.6.1 patched,
nothing has changed in README requirement AFAIK.
Is this a false positive? If not, any thoughts on how to make it go away?
Best,
Sam
