> can you tell me how to run the reproducer code exactly? :-)
What I did was:
1. Checkout your branch
2. Build + install the C++ library. The R package needs a folder with
something/include and something/lib where the ARROW_HOME environment variable
is set to "something".
3. You'll need R (`apt-get install r-base` is an old version but works) +
the package deps. The easiest way to get them is to install the version of
arrow from CRAN before installing the one for your branch (`R -e
'install.packages("arrow", repos = "https://cloud.r-project.org";)'`. This
Dockerfile might be helpful:
https://gist.github.com/paleolimbot/be77218201bdbd20353c084c74254824
4. `cd path/to/arrow/r && R CMD INSTALL .`
5. Open an interactive terminal, type in `R`, copy/paste this:
<details>
```r
library(arrow, warn.conflicts = FALSE)
tf <- tempfile()
write.csv(mtcars, tf, row.names = FALSE)
read_csv_arrow(tf)
parallel::mclapply(1:2, function(...) {
read_csv_arrow(tf)
})
```
</details>
Here's maybe some more raw output from lldb:
