That's to be expected, no one has backported the fixes for this yet.
Someone on the list started to, but then said they would wait for
someone else to do it, see this thread:
https://lore.kernel.org/r/fb4cce81-1e36-4887-a1e0-0cfd1a26693e@googlemail.com
So, until that happens, or one of my build-boxes accidentally gets
upgraded to gcc-15 and I'm forced to do it myself, this is going to stay
as-is.
thanks,
