Incompatibility with gcc 12.1.1

[dreamer2368]

It is observed from LC quartz that the current mgmol is not compatible with gcc 12.1.1. Below is the module list on quartz:

Currently Loaded Modules:
  1) jobutils/1.0   2) texlive/20220321   3) StdEnv (S)   4) git/2.36.1   5) python/3.10.8   6) cmake/3.26.3   7) paraview/5.11.0   8) petsc/3.18.3   9) gcc/12.1.1  10) tbb/2021.6.0  11) mvapich2/2.3.7  12) hdf5-parallel/1.14.0  13) mkl-interfaces/2022.1.0  14) boost/1.80.0

On ghcr-ci-test branch, the following commands compile mgmol well on LC quartz with gcc <= 11.2.1:

mkdir build && cd build
cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake_toolchains/quartz.default.cmake
make -j 16

However, with gcc 12.1.1, the following compilation error is returned:
