The workaround is to simply de-select ‘gcc_plugins’ in the kernel config, but if you need this, then there is a patch – and more info – at:\u00a0\u00a0 https:\/\/www.spinics.net\/lists\/kernel\/msg4674124.html<\/a><\/p>\n

I have applied this to Kernel 6.2 on Fedora 38 \/ GCC 13.0.1, and the kernel compile etc. now works OK..<\/p>\n
