Description david08741 2020-11-20 11:17:15 UTC 
Description of problem:
bash builtin `test -x /` does return 1, rather then returning 0.
This is only if running in a container on a ubuntu host.

Version-Release number of selected component (if applicable):
bash-5.0.17-2.fc33.x86_64

How reproducible:
always

Steps to Reproduce:
1. run a ubuntu host (e.g. 16.04 18.04 20.04)
2. podman run --rm -it registry.fedoraproject.org/fedora:rawhide /usr/bin/bash -c "test -x /" ;  echo $?

Actual results:
returns 1

Expected results:
returns 0

Additional info:
/ is executable, 
podman run --rm -it registry.fedoraproject.org/fedora:rawhide /usr/bin/test -x /
works as expected, so does zsh.
Also, podman and docker behave the same way.

Koshei list among others a glibc update since the last build [koshei] - but I am not sure whether the build [glibc] is the culprint.

Note that this breaks CI testing on travis, as no native fedora VMs are available.

This is a known issue triggered by a recent update of glibc.  See bug #1869030 comment #22 for details.
