raise SystemExit(main())

Error message

raise SystemExit(main())

What it means

This is not a thrown error but the standard Python idiom at the bottom of a CLI script: main() is executed and its integer return value is passed to SystemExit as the process exit code. Returning 0 means validation succeeded (all imported DLLs checked, no dynamic Visual C++ runtime found); any nonzero return or uncaught exception exits non-zero. It exists so CI and shell wrappers can detect validation failure programmatically.

Solutions

1. No fix needed when the exit code is 0 — validation passed
2. If the exit code is nonzero, re-run the script with stderr visible to see which validation step failed (missing binary, unexpected VC++ import)
3. Ensure the script is executed as the main module (`python script.py`), not imported, so this block runs

import subprocess
r = subprocess.run(["python", "agents/scripts/validate_windows_pe_dependencies.py", binary], capture_output=True)
if r.returncode != 0:
    raise RuntimeError(r.stderr.decode())

try:
    validate_pe(binary)
except SystemExit as e:
    if e.code != 0: handle_failure(e.code)

When it happens

Trigger: Running `python agents/scripts/validate_windows_pe_dependencies.py <binary>` from the command line or CI; the interpreter reaches the `if __name__ == "__main__"` block, calls main(), and raises SystemExit with the returned status code.

Common situations: CI pipelines validating that a built Windows PE binary does not dynamically link the Visual C++ runtime; developers running the validator locally before shipping a release binary.
