it
possible reproducer

I'm pretty sure that this reproducer is manifesting the same problem. So fa=
r we
have observed this with the debian beta and with fedora 36 beta both of whi=
ch
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 libra=
ry
dependencies seem to trigger the problem. However we did find that one libr=
ary
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.
