[issue39460] test_zipfile: test_add_file_after_2107() sometimes fails on Fedora Rawhide 3.x

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

> I failed to reproduce the issue on s390x Fedora Rawhide, Linux kernel 5.5.0-0.rc4.git2.1.fc32.s390x, glibc-2.30.9000-31.fc32.s390x.

I still cannot reproduce after a "dnf upgrade -y":

* Linux 5.5.0-0.rc6.git3.1.fc32.s390x
* glibc-2.30.9000-31.fc32.s390x

I tested attached mtime.c and Python test_add_file_after_2107() on nfs and tmpfs filesystems.

The s390x Fedora Rawhide 3.x buildbot worker where the bug occurs uses the same Linux kernel (5.5.0-0.rc6.git3.1.fc32.s390x) and it looks like the same glibc version (glibc 2.30.9000). Checking "rpm -q glibc" would say if it's exactly the same Fedora package.

David: what is the GCC version? (rpm -q gcc)
