It seems the current brew 1.12 using mpi for macos is acting flaky, and will segfault in a build script on building hdf5-sys.

An update of the homebrew repo means we now pull in hwloc version 2.5.0 (always failing), instead of version 2.4.0 (always working), which seems to be the only difference in installed packages. This could be relevant for debugging this issue.

Some further debugging results in the CI run here, where the build script was run under valgrind. It seems reading an environment variable fails after emitting an environment variable, although more debugging is necessary to confirm this.

Why this does not fail on other platforms remains a mystery. Could libloading load a faulty library which modifies unrelated memory?
