Thanks Enrico for the great guess, and Georgi for the details.
If I omit the space as seems to be implied in some documentation, changing
\verb <https://www.bankofcanada.ca/2006/03/working-paper-2006-3> .
to
\verb<https://www.bankofcanada.ca/2006/03/working-paper-2006-3> .
then the R CMD check error "\verb ended by end of line" happens on my
linux machine. I did not try replacing the space with another
deliminator, which I guess would now be the correct way to use \verb.
The solution of adding
\usepackage{url}
and changing to
\url{https://www.bankofcanada.ca/2006/03/working-paper-2006-3}.
does seem to work. (No "on CRAN" confirmation yet but I have not had the
immediate pre-test rejection that I got previously.)

When I run R CMD check on my Linux machine [*], I also
do not get an error. But here is a guess: The error
mentions \verb, and the LaTeX manual says that \verb
should be followed by nonspace character. But in the
vignette it is followed by a space. Maybe using \url
in the vignette could fix the error?
kind regards

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 errors:
! 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.
