- Disable lazy binding for installed shared objects. This provides
- additional security hardening because it enables full RELRO and a
- read-only global offset table (GOT), at the cost of slightly
- increased program load times.

Unless Python, PExpect and GDB with Python support are present, the

The final step when you have a simple test case is to report the bug.
