Not easily reproduced locally :-/. |
20 concurrent test runs on Anubis don't fail either. |
Try running the whole test suite with -j40. I'm seeing intermittent s

OK! |
This assertion happened to me in production usage, as I was running rr 5.4.0 in a Fedora 34 Beta Docker container. I was trying to reproduce my issue https://issues.apache.org/jira/browse/DISPATCH-782. I started the Docker with

The issue can be reproduced very easily (too easily, rr crashes way too easy, so I cannot use rr to look for crashes in my test). |
Can you reproduce this on rr tip? I haven't been able to reproduce this (while following the steps in https://issues.apache.org/jira/browse/DISPATCH-782). |
I can't, git tip does not crash for me. I let the loop run for an hour already and no crashes so far. The Fedora 34 rr package would already surely crash in all that time. I looked at the Fedora spec file and I saw nothing wildly different from how I compiled, https://src.fedoraproject.org/rpms/rr/blob/rawhide/f/rr.spec. |
@khuey Hi, may I ask for a rr release in order to get a version where this crash does not happen? My colleagues using Fedora are on the latest 5.5.0 version of rr which suffers from this. Having to build custom binary of rr from source is a significant inconvenience. Thanks. |
5.5.0 was released several months after you said you couldn't reproduce this: https://github.com/rr-debugger/rr/releases/tag/5.5.0 So if your colleagues are still seeing it it sounds like it wasn't fixed. |
🤦🏽 looks that way, given the way 5.5.0 seems to be crashing. I will try to look for a reproducer for myself

Just saw this on Anubis:
Seems like we also saw this on the KNL buildbot: https://ci.rr-project.org/#/builders/4/builds/93/steps/9/logs/stdio
