https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110789

--- Comment #5 from Peter Lezoch <pledr at gmx dot net> ---
I built a new gcc with --disable-avx2:

bash-5.2# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-pc-linux-gnu/12.2.0/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with: ../configure --prefix=/usr --disable-avx2
--enable-multilib --with-multili
b-list=m64,m32,mx32 --with-system-zlib --enable-default-pie
--enable-default-ssp --with-lon
g-double-128 --enable-languages=c,c++,fortran
Thread model: posix
Supported LTO compression algorithms: zlib zstd
gcc version 12.2.0 (GCC)
bash-5.2#

BUT: get the same internal error

     ==>> no improvement !!!
