Stan on Rstudio cloud not working

Hi,

I just came across RStudio Cloud with Stan -- https://rstudio.cloud/project/56157

This is awesome (and I wish it was the first link on the Stan website)!

That said, I can't seem to get it to work for me. When I try to fit the 8schools example, I get the error below. Note that when I test the C++ toolchain using pkgbuild::has_build_tools(debug = TRUE) the response is "TRUE".

Error in compileCode(f, code, language = language, verbose = verbose) :
Compilation ERROR, function(s)/method(s) not created! In file included from file1477c74dd4c.cpp:8:

Unfortunately, changes to the Stan compiler have caused compilation of code to exceed the 1 GB RAM limit of Cloud. The Stan and RStudio teams seem to be working together on this, but it does not seem to be resolved, yet.
