Segfault when executing empty query

[doerwalter]

When executing the following Python code:

import oracledb
db = oracledb.connect("user/pwd@db")
c = db.cursor()
c.execute("")

I get a segmentation fault:

$ python bug.py
zsh: segmentation fault  python bug.py

The following code:

import sys
import platform

print("platform.platform:", platform.platform())
print("sys.maxsize > 2**32:", sys.maxsize > 2**32)
print("platform.python_version:", platform.python_version())

reports:

platform.platform: macOS-15.5-arm64-arm-64bit-Mach-O
sys.maxsize > 2**32: True
platform.python_version: 3.13.5

and

print("oracledb.__version__:", oracledb.__version__)

reports

oracledb.__version__: 3.3.0

and

print(connection.version)

reports

18.0.0.0

oracledb is running in thin mode.

I have pushed a patch that should correct this issue and have initated a build from which you can download pre-built development wheels once it completes. You can also build from source if you prefer. If you can test your scenario and confirm the patch works as expected, that would be appreciated!

I'm not sure how to get the pre-built package from https://github.com/oracle/python-oracledb/actions/runs/16844487132

I don't see any obvious download links on that page.

@doerwalter there's a knack to getting that page to wake up / load and scroll correctly. Then you can see the 'Artifacts' section right at the bottom.

The direct link is https://github.com/oracle/python-oracledb/actions/runs/16844487132/artifacts/3724646394
