Hi Brice, hi Jeff,

I added printf inside that function, but ENOMEM does not come from there.

I tried with valgrind :
valgrind --track-origins=yes --log-file=output_valgrind --leak-check=full
--tool=memcheck --show-reachable=yes ./main_hybrid_bind_mem
==25687== Warning: set address range perms: large range [0x39454040,
==25687== Valgrind's memory management: out of memory:
==25687== newSuperblock's request for 4194304 bytes failed.
==25687== 34253180928 bytes have already been allocated.
==25687== Valgrind cannot continue. Sorry.
I attach the full output.
The code dies also using OpenMP pure code. Very misteriously.
