Sure:

Setting up libhdf5-openmpi-dev (1.10.10+repack-3.1ubuntu4) ...

Unfortunately not before mid-September.

By the way, I can also not reproduce the issue on my private computer.

But the Launchpad reporter said that they could reproduce the issue in a container, so maybe it would be interesting to ask them for it.
