How to reproduce

1. Install Fedora 42
2. curl -fsSL https://raw.githubusercontent.com/DeusData/codebase-memory-mcp/main/install.sh | bash
3. git clone --single-branch -b v2.16.0 https://github.com/Icinga/icinga2
4. cd icinga2
5. Create prompt.txt
6. /home/fedora/.local/bin/codebase-memory-mcp < prompt.txt
7. "Segmentation fault (core dumped)"
