xtimbeau opened a new issue, #40593: URL: https://github.com/apache/arrow/issues/40593
### Describe the bug, including details regarding any error messages, version, and platform. Using arrow 15 in R through dplyr, I got a crash (R session is crashed) when reading a dataset with to_duckdb(). On my dataset, pretty large composed of some parquet files -- I can send a dropbox link if needed, there are 2 columns that provoque the crash. There are encoded as factors (dictionary) and I suspect that different dictionaries for the different parquet are the cause of the crash. so `open_dataset(mydts) |> select(field1) |> to_duckdb() |> collect()` crash everything `open_dataset(mydts) |> select(field1) |> mutate(field1 = as.character(field1) |> to_duckdb() |> collect()` works and `open_dataset(mydts) |> select(field1) |> collect()` works too. I tried to rewrite the dataset loading it first (without duckdb) and then using write_dataset with no succes. using arrow 15.0.1 and duckdb 0.10 ### Component(s) R -- This is an automated message from the Apache Git Service.
