build failure with gcc13: -Werror=stringop-overflow

[nanoric]

GCC Version: gcc (GCC) 13.0.0 20220529 (experimental)

steps to reproduce:

# build gcc with git@master
cd / && git clone --depth 1 --single-branch --branch master https://github.com/gcc-mirror/gcc.git
GMP_VERSION="6.2.1" MPFR_VERSION="4.1.0" MPC_VERSION="1.2.1" \
  && cd /tmp && wget https://ftp.gnu.org/gnu/gmp/gmp-${GMP_VERSION}.tar.xz\
  && cd /tmp && wget https://ftp.gnu.org/gnu/mpfr/mpfr-${MPFR_VERSION}.zip \
  && cd /tmp && wget https://ftp.gnu.org/gnu/mpc/mpc-$MPC_VERSION.tar.gz \
  && cd /tmp && tar -xf gmp-$GMP_VERSION.tar.xz && cp -r gmp-$GMP_VERSION/ /gcc/gmp \
  && cd /tmp && unzip mpfr-$MPFR_VERSION.zip && cp -r mpfr-$MPFR_VERSION/ /gcc/mpfr \
  && cd /tmp && tar -xf mpc-$MPC_VERSION.tar.gz && cp -r mpc-$MPC_VERSION/ /gcc/mpc \
  && mkdir /gcc12 && rm -rf /tmp/*

cd /gcc \
  &&  CXX_FLAGS="-O3 -march=native" ./configure --disable-multilib --prefix=/gcc12 --with-arch=native --disable-werror

cd /gcc \
  && CXX_FLAGS="-O3 -march=native" make -j16 \
  && make install \
  && rm -rf /gcc

export CC=/gcc12/bin/gcc
export LD_LIBRARY_PATH=/gcc12/lib64:$LD_LIBRARY_PATH
export PATH=/gcc12/bin:$PATH
export PKG_CONFIG_PATH=/gcc12/lib64/pkgconfig:$PKG_CONFIG_PATH

# build tbb with that gcc:
cd /tmp && wget https://github.com/oneapi-src/oneTBB/archive/refs/heads/master.zip && unzip master.zip \
 && cd oneTBB-master && cmake -B build . -DCMAKE_BUILD_TYPE=Release \
 && CFLAGS="-O3 -march=native" CXXFLAGS="-O3 -march-native" make -j16 && make install

gcc13 is not currently part of the support matrix for oneTBB. We will support gcc13 in the future and provide a fix at the time. For now, you can disable the -Wstringop-overflow warning by adding -Wno-error=stringop-overflow to the TBB_WARNING_LEVEL variable in the corresponding cmake file. This file is located at <tbb_sources>/cmake/compilers/GNU.cmake.

See #823 for additional warnings you might need to suppress for now.

I find a issue of GCC which may relate to this problem. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106297

@nanoric The fix was implemented recently - https://github.com/oneapi-src/oneTBB/pull/1192. Please, verify and close the issue if resolved.
