It looks like guile's compiler and optimizer could be replacing the `getuid' and `setuid' calls with constant, compile-time values. Here is a test I performed: 1. Make directory with 770 owned by root and the `guixbuild' group. When guile is compiled with guix, I think the process is done under one of the guixbuilder<XX> users who have the `guixbuild' group. 2. Run guile under my regular user. 3. Try to `ftw' that directory. ftw detects it as a readable directory and then ends up throwing a "permission denied" error because it's not actually readable. If I compile guile manually under my regular user and try ftw on a different user, I observe the results that support my conclusion. System info: Guile 3.0.8.13-cc455 guix on amd64
