I had my kernel built with WERROR symbol set. It causes virtualbox-modules to fail to build with passing argument 1 of ‘memcpy’ discards ‘const’ qualifier from pointer target type I guess ebuild for virtualbox-modules should check kernel config and warn about it.

Created attachment 769841 [details] build log
You'll need to report this upstream to virtualbox but I'd suggest not building your kernel with werror when using third party modules.
I guess it is (somewhat) reported upstream https://www.virtualbox.org/ticket/20878, but it definitely lacks information. So, probably when new VB release comes out, it will support linux 5.17 hopefully. Had the same error since the release of kernel 5.17, but thankfully, it works upon disabling this WERROR option. Thanks for bringing this up.
virtualbox-modules-6.1.34 seem to work fine
Can confirm: virtualbox-modules-6.1.32 fails to compile virtualbox-modules-6.1.34 works just fine. I'm on gentoo-sources-5.17.7.
virtualbox-modules-6.1.34 fails with kernel sources 5.18 virtualbox-modules-6.1.36 compiles fine
I tried 7.0.10 with kernel 6.1.41 (latest stable) compiled with WERROR and it works. I'll close the bug, but if it happens again with a new kernel or a new release, please open a bug with upstream instead.
