I have been a little too busy and have not yet upgraded to 18.04
so I can't attempt to replicate -- but it _looks_ just like a
garden variety binary mismatch.

We _know_ R 3.5.* requires _all_ binary packages to be
reinstalled and it is easy to miss one.  So unless G?ran shows us
a generally reproducible bug I will suspect that this is simply a
local deployment issue.

I suspect that too, since the segfault does _not_ occur if run  R
via RStudio. _But_, I have run 'update.packages(checkBuilt =
TRUE)', and that should take care of reinstalling, right?

Maybe it somehow is an issue with devtools::install_github.

If you follow the error traceback (from the bottom of the stack to
the top), the most recent package involved is 'curl'.  It appears
that the segfault occurs when it is loaded.  You probably get the
same if you attempt:

library(curl)

in a fresh R session.  If so, as Dirk suggests:

make sure to reinstall 'curl'.  If that solves it, it's likely that
other packages have the same issue, so you probably want to start
from a clean slate and wipe your current package library, e.g.
unlink(.libPaths()[1], recursive = TRUE).
