["Nicola Crane (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-14519?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nicola Crane updated ARROW-14519:
---------------------------------
    Description: 
When I run the R code below, it results in a segfault if one of the tables contains a list column.
{code:r}
library(arrow)
library(dplyr)

basic_tbl <- arrow_table(
  tibble::tibble(
    x = 1:3,
    y = c("a", "b", "c")
  )
)

basic_tbl2 <- arrow_table(
  tibble::tibble(
    x = 1:3,
    z = c(T, F, T)
  )
)

list_tbl <- arrow_table(
  tibble::tibble(
    z = list(c("first", "list", "col", "row"), c("second row ", "here")),
    x = 1:2
  )
)

# works
left_join(basic_tbl, basic_tbl2) %>%
  collect()

# segfaults
left_join(basic_tbl, list_tbl) %>%
  collect()

{code}

  was:
 
{code:r}
library(arrow)
library(dplyr)

basic_tbl <- arrow_table(
  tibble::tibble(
    x = 1:3,
    y = c("a", "b", "c")
  )
)

basic_tbl2 <- arrow_table(
  tibble::tibble(
    x = 1:3,
    z = c(T, F, T)
  )
)

list_tbl <- arrow_table(
  tibble::tibble(
    z = list(c("first", "list", "col", "row"), c("second row ", "here")),
    x = 1:2
  )
)

# works
left_join(basic_tbl, basic_tbl2) %>%
  collect()

# segfaults
left_join(basic_tbl, list_tbl) %>%
  collect()

{code}
