[R-pkg-devel] How to debug segfault when running build -> document in Rstudio that includes TMB module

[James Lamb]

Carl,

Consider performing these tasks without the use of the 'devtools' package,
running the following from a shell.

```shell
R CMD build .
R CMD INSTALL --with-keep.source ./SPAS_*.tar.gz

# (assuming you use roxygen2)
Rscript -e "roxygen2::roxygenize(load = 'installed')"

R CMD check --as-cran ./SPAS_*.tar.gz
```

If those commands are successful, then you know the problem lies somewhere
in the difference between that approach and what 'devtools' does, which
might help to narrow it down.

Cheers,

-James
