The problem is not in the Warning from the example but from the \verb commands in the references.
You use space to delimit the argument of \verb and I was surprised that it worked since TeX ignores spaces after commands.
Apparently, this has been an exception for \verb but now this feature is considered a bug and hs been recently fixed, see the atacjexchange question below and the relevant paragraph from LaTeX News. Probably the linux machines have updated their TeX installations.
In short, changing the space tp say + delimiter for \verb command should fix the issue.
Avoid problematic spaces after \verb
If a user typed \verb␣!~!␣foo instead of \verb!~!␣foo
by mistake, then surprisingly the result was “!~!foo”
without any warning or error. What happened was that
the ␣ became the argument delimiter due to the rather
complex processing done by \verb to render verbatim.
This has been fixed and spaces directly following the
command \verb or \verb* are now ignored as elsewhere.

Subject: [R-pkg-devel] CRAN check texi2dvi failure
I am trying to debug a problem that is appearing in the linux and Solaris checks, but not Windows or Mac checks, of my package tsfa as reported at https://cran.r-project.org/web/checks/check_results_tsfa.html
The problem is with re-building the vignette
this is package 'tsfa' version '2014.10-1'
checking re-building of vignette outputs ... [6s/9s] WARNING
Error(s) in re-building vignettes:
Running 'texi2dvi' on 'Guide.tex' failed.
! LaTeX Error: \verb ended by end of line.
In responding to the threat of removal I have also fixes some long standing warnings about adding imports to the NAMESPACE. The new version builds with --as-cran giving no errors or warnings with both R-devel on win-builder (2021-01-07 r79806) and on my linux machine (R 2021-01-08
r79812 on Linux Mint 19.3 Tricia). When I submit it to CRAN the Windows build is OK but the same error happens at the 'texi2dvi' step in the debian vignette re-build.
This seems to happens after an example that correctly has a warning message (about Heywood cases). In my linux build the the warning happens but the message does not appear in the pdf output, so one possibility is that the handling of the warning on the CRAN Unix check machines fails to produce clean tex or suppress output. Another possibility is that my build using --as-cran is different from the actual CRAN build options.
For example, my 00check.log shows
* checking package vignettes in ‘inst/doc’ ... OK
* checking re-building of vignette outputs ... OK
* checking PDF version of manual ... OK
* checking for non-standard things in the check directory ... OK ...
so I am not sure if it uses texi2dvi. (I haven't used dvi myself for a long time.)
I'm not sure how to debug this when I can't reproduce the error.
Suggestions would be appreciated.
