This is one very strange bug. Why would the mere fact that h5py is
loaded affect what subprocess does?
Yes, this is completely mysterious. However, the bug is real.
It is probably an upstream problem. I would love to forward the
present report upstream, but I have no idea to where send it.
I am inclined to raise the severity of this bug report from
“important” to “serious”, because it is blocking Bug#938925, which has
severity “serious” and is preventing xmds2 to enter testing.
h5py have done some work on their mpi support (cf.
https://github.com/h5py/h5py/issues/1364). They've created pytest-mpi
to help with tests. It's currently in the debian NEW queue.
Thibaut's idea in bug#944769 to ignore mpi if there's only one process
will be relatively straightforward to implement I think (I've had other
tasks to finish before I get onto that). I guess that will fix (or at
least workaround) this problem.
Might be worth bringing to the attention of the subprocess developers. I
figure they'll either be interested to know about the problem or will
have a simple explanation.
