Cannot install development version

Summary:

I'm trying to build the feature/survival branch from source, using "Install and Restart" in the RStudio console for the rstanarm.Rproj R project.

But after taking forever (some time overnight), it eventually fails, this time with this error in the build window:

Execution halted

Exited with status 1.

Reproducible Steps:

As described above.

RStanARM Version:

feature/survival branch.

R Version:

4.0.3

Operating System:

Windows 10

Start by reproducing the development-branch installation on Windows 10 with R 4.0.3 and inspect the compiler output for stan_files/continuous.cc, especially the assembler "too many sections" and "file too big" errors. Compare the package build configuration and the R Makeconf referenced in the log; done means the feature/survival branch installs successfully.
