Segmentation fault in runner_do_recv_part

Hey, when running EAGLE_low_z/EAGLE_6 with the following command: mpirun -n 2 ../../swift_mpi -e --eagle --cosmology --threads=4 eagle_6.yml I get very quickly a segmentation fault (before the first step according to the output in the terminal). I have compiled swift with --disable-hand-vec --disable-optimization --with-subgrid=EAGLE (I was also getting a segmentation fault with the optimization).

When running inside GDB, I am not able to catch the error. With Valgrind, I obtained the following output:

==16473== Process terminating with default action of signal 11 (SIGSEGV)
