            Bug ID: 107483
           Summary: c++: fatal error: Killed signal terminated program
                    cc1plus due to out of memory
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seehearfeel at 126 dot com
  Target Milestone: ---

When build llvm used with c++ 13, c++: fatal error: Killed signal terminated
program cc1plus due to out of memory.

https://reviews.llvm.org/D136362#3895385

I can reproduce this issue on x86_64 used with the latest gcc.

(1) Install Fedora36
https://download.fedoraproject.org/pub/fedora/linux/releases/36/Workstation/x86_64/iso/Fedora-Workstation-Live-x86_64-36-1.5.iso

$ uname -a
Linux fedora 5.17.5-300.fc36.x86_64 #1 SMP PREEMPT Thu Apr 28 15:51:30 UTC 2022
x86_64 x86_64 x86_64 GNU/Linux

(2) Install some packages
sudo yum -y install llvm clang g++ cmake ninja-build bison flex texinfo

$ gcc --version
gcc (GCC) 12.2.1 20220819 (Red Hat 12.2.1-2)
$ c++ --version
c++ (GCC) 12.2.1 20220819 (Red Hat 12.2.1-2)
$ clang --version
clang version 14.0.5 (Fedora 14.0.5-1.fc36)
$ clang++ --version
clang version 14.0.5 (Fedora 14.0.5-1.fc36)

(3) Build llvm

git clone https://github.com/llvm/llvm-project.git
mkdir -p llvm-project/llvm/build
cd llvm-project/llvm/build
cmake .. -G "Ninja" -DLLVM_TARGETS_TO_BUILD="X86" \
         -DLLVM_ENABLE_PROJECTS="clang;lldb" \
         -DCMAKE_BUILD_TYPE=Release \
         -DLLVM_BUILD_RUNTIME=OFF
ninja
ninja check-lldb
This is OK used with gcc/c++ 12.

(4) Update gcc to the latest version
git clone git://gcc.gnu.org/git/gcc.git
cd gcc
./contrib/download_prerequisites
mkdir -p build
cd build
../configure --prefix=/usr/local/gcc --enable-checking=release
--enable-languages=c,c++ --disable-multilib
make
sudo make install
export PATH=/usr/local/gcc/bin/:$PATH
export LD_LIBRARY_PATH=/usr/local/gcc/lib64:$LD_LIBRARY_PATH

$ gcc --version
gcc (GCC) 13.0.0 20221029 (experimental)
$ c++ --version
c++ (GCC) 13.0.0 20221029 (experimental)

(5) Do the above (3) again used with gcc/c++ 13

git clone https://github.com/llvm/llvm-project.git
mkdir -p llvm-project/llvm/build
cd llvm-project/llvm/build
cmake .. -G "Ninja" -DLLVM_TARGETS_TO_BUILD="X86" \
         -DLLVM_ENABLE_PROJECTS="clang;lldb" \
         -DCMAKE_BUILD_TYPE=Release \
         -DLLVM_BUILD_RUNTIME=OFF \
         -DCMAKE_C_COMPILER="/usr/local/gcc/bin/gcc" \
         -DCMAKE_CXX_COMPILER="/usr/local/gcc/bin/c++"
ninja
ninja check-lldb
We can see that "ninja check-lldb" failed due to OOM
used with gcc/c++ 13.

--- Comment #1 from Tiezhu Yang <seehearfeel at 126 dot com> ---
dmesg shows that c++ 13 is getting killed by the OOM-killer due to using too
many resources. Adding 64G swap, it is still OOM. c++ 12 has no problem.

Can you attach the preprocessed source of which file gcc is failing out of
memory on?
