klin333 opened a new issue, #2819:
URL: https://github.com/apache/arrow-adbc/issues/2819
### What happened?
Calling `adbc_connection_get_objects` seems to crash R (ie total crash of R
session), as soon as R's garbage collection is run. Maybe segfault somewhere
from freeing of resources when gc() is triggered. Pretty sure gc() triggers the
crash because the crash will happen randomly a few seconds after calling
`convert_array_stream` ie not immediately after the call but randomly after it
- calling gc() manually will immediately trigger the R crash.
```{r}
uri <- "SECRET"
db <- adbcdrivermanager::adbc_database_init(adbcsnowflake::adbcsnowflake(),
uri = uri)
drivermanager_con <- adbcdrivermanager::adbc_connection_init(db)
nfo <- adbcdrivermanager::adbc_connection_get_objects(drivermanager_con,
depth = 3L, table_name = 'FLIGHTS') # can leave out depth and table_name and
still will crash
res <- nanoarrow::convert_array_stream(nfo) # can also substitute this line
for simple console print of nfo, and still will crash
# sessionInfo()
gc() # trigger for crash (or just wait a bit for gc to run itself and will
also crash)
```
sessionInfo()
```
