Well, the plugins work with all the other compiler versions all the various CI systems use. :) For example, I don't see this with distro cross compilers: $ mipsel-linux-gnu-gcc --version mipsel-linux-gnu-gcc (Ubuntu 12.3.0-1ubuntu1) 12.3.0 I suspect this is a problem with the kernel.org crosstool builds? I'm CCing Arnd, who might know more about this. -Kees -- Kees Cook
