To help me understand this bug, could you please post the key factors of your environment for me to reproduce? For example, your GNU/Linux distribution by the output of lsb_release -a your filesystem mount options by, mount and your glibc, gcc, binutils versions by, ldd --version gcc --version ld --version Thanks!

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial I cannot reproduce this bug with my setup of Ubuntu 16.04, there might be some other causes we are not aware of. Does the same error message appear when you run the bootstrap script again?
Plus, change a location to install, for example: /opt/gentoo, /tmp/gentoo, etc.
Rerunning it didn't help, even with -j1 (via answering the question about number) Trying a different path now. Did you set your /home and /home/user permissions the same way?

The other path worked.

Thanks all.
Hi Benda, can the build be fixed to not rely on access to all parent directories? While this workaround "works", it's far from a great solution. I'd need to reinstall Prefix after every reboot, since the other path is in tmpfs.
we have no means to work around permission bits with Prefix
