Hi Kees, I can provide live ssh access to my system exhibiting the issue. My system is a lot more stable due to using openrc rather than systemd, for me GCC seems to be the only binary affected. Would that be helpful?

You should be able to extract the binaries from this initrd image and the "mount" command,
for example, should be one of the affected binaries.

In dmesg, do you see any of these reports?

pr_info("%d (%s): Uhuuh, elf segment at %px requested but the memory is mapped already\n", task_pid_nr(current), current->comm, (void *)addr);

I'll check that.

I don't see anything out of order in the "mount" binary from the above
initrd. What does "readelf -lW" show for the GCC you're seeing failures
on?

I'm not 100% sure whether it's the mount binary that is affected. What
happens is that once init takes over,
I'm seeing multiple "Segmentation Fault" message on the console until
I'm dropped to the initrd shell.

I can check what dmesg says.
