[Bug]: pylibseekdb 1.2.0 / 1.3.0 SIGSEGV on macOS 15.1.1 arm64 (embedded mode)

Describe the bug

Summary
pylibseekdb 1.2.0 and 1.3.0 crash with SIGSEGV (segmentation fault) on macOS 15.1.1 arm64 when using embedded mode (Client(path=..., database='test')). Only pylibseekdb 1.1.0 works correctly on this platform.

Environment

Fast reproduce steps

import pyseekdb

client = pyseekdb.Client(path="./seekdb_data", database="test")
# ↑ SIGSEGV here with pylibseekdb >= 1.2.0

Or via CLI:

pip install pyseekdb==1.3.0 pylibseekdb==1.3.0
python -c "import pyseekdb; c = pyseekdb.Client(path='./data', database='test')"
# Segmentation fault: 11

Expected behavior

Client() initializes successfully in embedded mode, same as pylibseekdb 1.1.0.

Actual behavior

• pylibseekdb 1.1.0: Works correctly. Can create collections, upsert data, and run hybrid_search with HNSW index.
• pylibseekdb 1.2.0: Crashes with SIGSEGV at seekdb.open().
• pylibseekdb 1.3.0: Crashes with SIGSEGV at seekdb.open().

The crash is a hard segfault (signal 11), not a Python exception. No traceback is produced.

Additional context

Workaround

Pin pylibseekdb to 1.1.0 while keeping pyseekdb Python SDK at 1.3.0:

pip install pyseekdb==1.3.0 pylibseekdb==1.1.0

This combination works on macOS 15.1.1 arm64 with full functionality (HNSW index, hybrid_search, RRF ranking, etc.).

Additional Notes

• The issue is specific to embedded mode. I did not test server mode.
• pyseekdb's PyPI description mentions embedded mode supports "Linux and macOS 15+", and 1.1.0 does work as advertised.
• The crash appears to be in the native library (pylibseekdb), not the Python SDK layer.

Reproduce the crash with pyseekdb 1.3.0 and pylibseekdb 1.2.0 or 1.3.0 using Client(path="./seekdb_data", database="test") and compare it with pylibseekdb 1.1.0. Start at the embedded-mode path reached by seekdb.open(); done means Client initializes without SIGSEGV on macOS 15.1.1 arm64 while preserving the reported embedded functionality.
