["warnes (via GitHub)" <gi...@apache.org>]

warnes opened a new issue, #47001:
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
