GCC kernel plugin "Randomize layout of sensitive kernel structures" makes the build abort with an ICE

[admnd]

With "Randomize layout of sensitive kernel structures" (GCC plugins) turned on in the kernel configuration, the compilation terminates with a GCC Internal Compiler Error:

Perfectly reproducible with branch "dwa-x1850" at commit 1e9a9b1156f7bb7b38c6fe667429740757969835 Tested with Linux 5.17.14 + Gentoo patches, and GCC 11.3.0 Disabling the "Randomize layout of sensitive kernel structures" GCC plugin solved the issue for me. No bug report submitted yet.
