mpi_init crashes with ifx

[Jaapw]

Dear support

I am having troubles with compiling and running a simple code. I ask this since our production code seems to become unstable using ifx.

I am using Rocky9 , Intel OneAPI 2024.2

I have a simple program:

program hello
use mpi_f08
implicit none
integer :: ierr
call MPI_Init(ierr)
call MPI_Finalize(ierr)
end program hello

I use the following:

module load oneapi/tbb/2021.13
module load oneapi/compiler-rt/2024.2.1
module load oneapi/compiler/2024.2.1
module load oneapi/mpi/2021.13
export I_MPI_F90=ifx

I compile with:

/cm/shared/apps/oneapi/2024.2.1/mpi/2021.13/bin/mpif90 -g -traceback -O0 -check all test.F90 -o test

Running the program gives:

./test
