There is no such message (as you cite below) in the R-devel archives:
https://stat.ethz.ch/pipermail/r-devel/2017-November/thread.html
Hence it was never posted for some reason
(You may have *sent* it, but it never arrived "safely")

installing the required packages. Then when the vignettes are being created, it
crashes. Today I installed the latest versions of Rtools, MikTex and R-devel
and still got the same error. We have also replicated this on another machine.
I am able to successfully build the package in this way with R 3.4.3.

To make this reproducible, indeed, I also get
problem, possibly the same as you on my Linux machine (Fedora 26):
1. Get httk_1.7.tar.gz from https://cran.r-project.org/package=httk
2. unpack (for me:)
tar xf httk_1.7.tar.gz
3.
R-devel CMD build httk
I get the following.
Notably after having waited several minutes at the prompt
(line of output):
'* creating vignettes '

------------------------------------------------------------------------
I've seen this (segfault, triggered from stringr stuff) before,
occasionally and always thought it was a consequence of a messup
(different R versions and package installations in libraries I
use on the same computer....), but now I have convinced myself
that this is not the case: I can easily reproduce the above using
tools::buildVignettes(dir = "<mypath_to>/httk")
==> So I'd suggest there's a pretty low-level bug somewhere.
- Either in 'stringr' or 'stringi' in their C code using
things they should not (because not in R's API),
which now shows in R-devel where many "inner workings" have been
modified (key "ALTREP")
- or in R-devel .. in these new "inner workings".
I don't have time to dig further at the moment.
Thank you, Robert, for your report!
