Bug 720684 – sci-biology/foldingathome-7.6.9: general protection fault in libc-2.31.so

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description George Diamantopoulos 2020-05-02 17:25:44 UTC]

After upgrading to 7.6.9, FAHClient fails to start with the following error:

kernel: traps: FAHClient[1424] general protection fault ip:7f0df1fc9efc sp:7fffc504c240 error:0 in libc-2.31.so[7f0df1f65000+145000]

Anyone else getting this? Any known workarounds? I'm running an ~amd64 system.

Reproducible: Always

Steps to Reproduce:
1. Upgrade to 7.6.9
2. Start the service via systemd unit

Thank you for the report. We need to have all information at hand before ticket assignment. That is why I ask you to 
* attach the logs and 
* paste the emerge info 
as described on 
https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket

Precursors for general protection fault can be in the warnings of the compile log.

Please reopen this ticket (Status:UNCONFIRMED) afterwards.

Does this issue still exist with 7.6.13 ?

I'm not the original reporter, but I think I'm hitting the same issue. dmesg contains the folowing:
