However, the main issue is that LPF is using a non-standard "weak" qualifier, which is GCC-specific, for auto initialization.
It manifests mostly for MPICH at the moment on Ubuntu 22.04. There, following can be seen:
pkg-config --libs mpich
-Wl,-Bsymbolic-functions -flto=auto -ffat-lto-objects -flto=auto -Wl,-z,relro -lmpich -lpthread -lhwloc -lfabric
CMake uses this to set MPI_C_COMPILE_FLAGS, which LPF uses.
After that, MPI tests run with lpfrun wrapper fail with the message that MPI initialization was attempted twice (since LPF_MPI_AUTO_INITIALIZE was incorrectly 0).
Workaround: the MPI_C_COMPILE_FLAGS can be ommitted from LPF.
