joellubi opened a new issue, #1841:
URL: https://github.com/apache/arrow-adbc/issues/1841
### What happened?
When using both the snowflake driver and the flightsql driver in the same
python program, the process crashes with a segmentation violation. Using one of
these drivers at the same time as the postgres driver does not cause a crash,
which makes it seem like there might be an issue in the common Go memory
management of the snowflake and flightsql drivers.
### How can we reproduce the bug?
Minimal Reproduction:
```python
import adbc_driver_flightsql.dbapi
import adbc_driver_snowflake.dbapi
adbc_driver_flightsql.dbapi.connect("grpc+tcp://localhost:8080")
adbc_driver_snowflake.dbapi.connect()
```
Result:
```

### Environment/Setup
Reproduces with:
```toml
adbc-driver-snowflake = { file =
"/path/to/adbc_driver_snowflake-1.0.0-py3-none-macosx_10_15_x86_64.whl" }
adbc-driver-flightsql = { file =
"/path/to/adbc_driver_flightsql-1.0.0-py3-none-macosx_10_15_x86_64.whl" }
```
and:
```toml
adbc-driver-snowflake = "^0.11.0"
adbc-driver-flightsql = "^0.11.0"
```
Does NOT reproduce with:
```toml
adbc-driver-snowflake = "^0.10.0"
adbc-driver-flightsql = "^0.10.0"
```
However, as I've tried pushing against various edge cases I have been able
to get some segmentation violations with `0.10.0` too, but haven't yet isolated
the specific behavior that causes it in that version.
