The geo stack is complicated. I have no pointers. But on the Debian testing machine (i.e. something "close" your Ubuntu setup) I use for Rcpp reverse depends, I recently recompiled an entire stack "in bulk and anger" simply because I could not pin-point where such a segfault came from. What you could is try to mimick the Actions setup (by starting with a Ubuntu 20.04 container, Rocker has some as eg rocker/r-ubuntu:20.04 giving you a head). You can then start to replace .deb by .deb by hand-compiling and see which one is 'guilty'. Michael could then rebuild that .deb. Sadly I do not know of any other shortcuts.
