Research direction

Reproduce the failure with the reported pywrap command and ocp.toml configuration. Start in bindgen/header.py at parse(), especially the get_includes() handling on line 707, then trace the callers through process_header() and ModuleInfo. Done means identifying the include that has no file location and establishing how the parser should handle it.
