[R-SIG-Mac] Installing CRAN binary packages with R 4.0 installed from source crashes R

[Hervé Pagès]

Hi Simon,

After installing R 4.0 alpha from source on a macOS Mojave system, R 
won't let me use type="both" to install CRAN packages. I get:

   Error in install.packages("rJava", type = "both", repos = 
"https://cran.r-project.org") :
     type == "both" can only be used on Windows or a CRAN build for macOS

OK so this suggests that the CRAN binary packages for R 4.0 are not 
compatible with my R. Surprisingly though using type="mac.binary" 
doesn't complain and lets me install these binaries. But then trying to 
load them causes segfaults. I've tried this with rJava, Rcpp, ggplot2, 
and doing library() on any of them crashes my session. Note that 
installing all these packages from source works without any problem.

So my questions are: is it the case that CRAN binary packages are not 
meant to be used with an R 4.0 installed from source? If yes then why 
isn't type="mac.binary" blocking this like type="both" does?

Thanks,
H.
