    Do you have any reference on this, because the ICE does not occur when
    building the kernel with a vanilla gcc 15.1.0 build from git. (see
    Message #10)

    OTOH I do get the ICE with all Debians gcc-15 versions I tested (15.1.0-1 to 15.1.0-4).

    - please check with the current upstream branch.

    - please check with the same configure options and build
    targets as found in Debian.

    You are right, this seems indeed to be a kernel bug. The ICE occurs when
    gcc (15.1.0) is compiled with --enable-checking=misc (which is included in --enable-checking=all).

    I also simplified the file that produces the ICE to three statements
    (see attachment).

    Thanks for your suggestions.
