possible reproducer

I'm pretty sure that this reproducer is manifesting the same problem. So far we
have observed this with the debian beta and with fedora 36 beta both of which
use glibc 2.35

This only seems to happen with some libraries which have some dependencies. We
have not yet been able to figure out a common denominator about which library
dependencies seem to trigger the problem. However we did find that one library
which is part of the distro which reliably seemed to be frequently involved in
the failing test cases, hwloc.

LD_PRELOAD the hwloc library prevents the problem from happening.
