Hi Bruno:
I am compiling from the hg development source but the warnings have been
around for a long time and you should be able to see them with released
versions as well. The following hg ids reproduce it for me:
* 1ecc78a2319d @
* c31552356c72 (bytecode-interpreter) tip
Compilation flags:
```
export CC="clang"
export CXX="clang++ --std=c++17"
export F77="gfortran"
export CFLAGS="-pipe -march=native -O3"
export CXXFLAGS="-pipe -march=native -O3"
export FFLAGS="-pipe -march=native -O3"
export LIBS="-ljemalloc"
```
Configure options:
```
../configure --enable-std-pmr-polymorphic-allocator --enable-largefile
--enable-year2038 --enable-threads=posix --enable-64 --enable-openmp
--enable-readline --enable-fftw-threads --disable-java --enable-docs
--disable-lib-visibility-flags --with-openssl=yes --with-qt=6
