When FEATURES="distcc" is enabled sys-libs/libxcrypt-4.4.25:0/1::gentoo builds but causes lots of issues. Any other packages that try to compile with crypt support fail including sys-libs/pam-1.5.1_p20210622-r1::gentoo which making logging in on the console, su-ing, sudo-ing, and logging in via ssh impossible. Reproducible: Always Steps to Reproduce: 1. Enable FEATURES="distcc" 2. emerge -1v libxcrypt 3. emerge -1v pam Actual Results: pam fails to compile, and pam is broken making logins impossible. Other packages that fail to build are python, mailutils, and screen. Expected Results: pam and other packages should compile and function. Most of the compilation failures have messages referencing crypt. The distcc server seems to still be using glibc crypt. This is especially annoying because the pam failures make it very difficult to become root so you can actually fix the issue.

Please provide builds logs for the failing packages.

Created attachment 750477 [details] pam errors These are the messages generated by pam in syslog when libxcrypt is in its broken state by using distcc. Even though pam was previously built with a good libxcrypt, when I rebuilt libxcrypt, it immediately stopped working.

It appears much of this was caused by using distcc on a docker image that was deprecated (gentoo/stage3-amd64:latest) causing it to have an ancient version of gcc (x86_64-pc-linux-gnu-9.3.0). libxcrypt and pam seem to compile and work just fine when using an up to date docker image with the latest stable gcc (x86_64-pc-linux-gnu-11.2.0).

So what's the word if I've already upgraded libxcrypt a few weeks ago using gcc 9.3 and 9.4 on various machines, and it seems to work fine (until the newer libxcrypt ebuild complains about gcc<10 just now)? See the above forum thread for more details...

See the above > forum thread for more details... I suppose I could keep the check just for distcc (I think the configure check only gets confused in that case). I'll reply to the rest on the forums.
