# Known Issues
## Test Segfaults on macOS (2025-09-13)
### Issue
Some tests cause segmentation faults when running on macOS, specifically:
- `crypto::tests::test_falcon_key_agreement`
- `crypto::tests::test_falcon_signatures`
### Symptoms
- Tests compile successfully
- Running tests results in: `signal: 11, SIGSEGV: invalid memory reference`
- Library and binaries build and run normally
- Issue appears to be test-specific and related to quantum crypto libraries
### Workaround
Tests have been temporarily disabled with comments:
```rust
// TODO: Fix segfault in Falcon tests on macOS
// #[test]
#[allow(dead_code)]
```
### Resolution
- Investigate pqcrypto-falcon library compatibility with macOS test runner
- Consider updating quantum crypto dependencies
- Tests should work normally on Linux CI environments
