emerge --info

Issue is reproducible. Remerge of kernel gentoo-sources did not change the issue.
Compilation works <4.15.0.

Comment 2 Georgy Yakovlev archtester gentoo-dev 2018-04-16 05:32:05 UTC
It's failing because of CONFIG_DEBUG_INFO_SPLIT in the kernel config. try disabling that.

I'm currently working on linux-mod.eclass and can look at the issue a bit deeper, seems it needs some patching or sandbox massage.
