Description Edjunior Barbosa Machado 2020-01-27 14:58:47 UTC

Also reproducible with strace-4.24-4.el7 on RHEL-7.8-20200122.n.0 x86_64, ppc64 and ppc64le.

+++ This bug was initially created as a clone of Bug #1794490 +++

Description of problem:
Some of the ipc_* tests are occasionally failing on rhel-8.2 gcc-toolset-9-strace-5.1-4.el8. From the testsuite run output:

...
PASS: ipc_msgbuf-Xabbrev.gen.test
FAIL: ipc_msgbuf-Xraw.gen.test
PASS: ipc_msgbuf-Xverbose.gen.test
PASS: ipc_sem.gen.test
PASS: ipc_sem-Xabbrev.gen.test
PASS: ipc_sem-Xraw.gen.test
PASS: ipc_sem-Xverbose.gen.test
FAIL: ipc_shm.gen.test
FAIL: ipc_shm-Xabbrev.gen.test
PASS: ipc_shm-Xraw.gen.test
FAIL: ipc_shm-Xverbose.gen.test
...

For some reason, it is usually no longer reproducible when trying to rerun the testsuite. On the last testrun, it happened only in aarch64 and x86_64 (it ran successfully in s390x and ppc64le)

Version-Release number of selected component (if applicable):
gcc-toolset-9-strace-5.1-4.el8

How reproducible:
Occasionally

Steps to Reproduce (as non-root user):
1. rpm -ivh gcc-toolset-9-strace-5.1-4.el8.src.rpm
2. rpmbuild -bc ~/rpmbuild/SPECS/strace.spec
3. cd ~/rpmbuild/BUILD/strace-*/
4. chmod u+x tests/*.test tests-m32/*.test tests-mx32/*.test
5. make -k check STRACE=/opt/rh/gcc-toolset-9/root/usr/bin/strace TIMEOUT_DURATION=1500

Actual results:
Occasional failures

Expected results:
No failures

Additional info:
RHEL-8.2.0-20200107.n.1
