Hi, I am trying to implement a program with hybrid MPI + Threads parallelization. In the following example, if I comment out all MPI-related lines, the code runs without any problem. However, if I run the code with the MPI lines, Julia crashes in a probabilistic manner (crash probability around 50%…

It seems that the issue comes from the system MPI. By using the automatically downloaded MPICH, the problem does not occur.
