[gentoo-user] gentoo-sources-6.7.7 build error

[ralfconn]

I have a build error with latest gentoo-sources (~amd64): # eix -I 
gentoo-sources Installed versions: 6.7.6(6.7.6)^bs(10:37:31

This is on a gentoo box with mixed profile 
(local:no-multilib-hardened-desktop (dev)). The vanilla kernel 
downloaded from kernel.org - with same config - has the same build 
error. I thought it could be a hardened-related issue, but a different 
gentoo box with an hardened-dektop profile builds fine. The kernel 
config is different, though. By the way, looking at the failing source 
it seems to me that the error is a false positive. I suppose nobody else 
is seeing this, I see no reports on the net. Any hints? Should I file a 
bug upstream? thanks, raffaele
