URL: https://github.com/apache/arrow/issues/47001
### Describe the bug, including details regarding any error messages,
version, and platform.
This R script causes a segfault with the current version of the R arrow
package:
``` R
library(arrow)
iris_table1 <- arrow_table(iris)
iris_table2 <- arrow_table(iris)
iris_record <- record_batch(iris)
. <- concat_tables(iris_table1, iris_table2)
. <- concat_tables(iris_table1, iris_record)
venv➜ gtrader git:(prod) ✗
```
For example:
```
$ R CMD BATCH /tmp/arrow_concat_tables_segfault.R
/Library/Frameworks/R.framework/Resources/bin/BATCH: line 60: 93251
Segmentation fault: 11 ${R_HOME}/bin/R -f ${in} ${opts} ${R_BATCH_OPTIONS} >
${out} 2>&1
$ cat arrow_concat_tables_segfault.Rout
