Hello Andreas,

maybe https://bugs.gentoo.org/672856 is related.

They say:

What Linux kernel version do you have?

thanks for digging this up!

It happens on my laptop, with kernel 4.9.0. But I thought it also happens
on bayfront (kernel 4.19.1), which offloads to harbourfront (kernel 4.19.8).
I will try the latter two again.

Actually I did not remember well, it did compile now on bayfront/harbourfront.
So this seems to be very transient and does not occur on the most recent Guix.
I am closing this bug, and we can open it again if there is a need; the
information on the potential patch will remain online anyway.

Qt should definitely not require a kernel more recent than what libc
requires.  If this patch solves that, we should probably apply it (in
‘staging’ I guess.)

Thanks,

Oh dear, this would certainly cause problems on RHEL 6 and 7.  Thanks
for trying to fix it!

The patch makes qtbase build on my laptop, so I pushed it as commit
69c15ad8a46c8e5f319a73ee5891bcd1bf0600c5. The bug can remain closed, I hope.

Thanks again, Danny!
