----------------------------------
Summary: [proton-c] ThreadSanitizer data race between
`pni_logger_init` and `_dl_fini`
Key: PROTON-2530
URL: https://issues.apache.org/jira/browse/PROTON-2530
Project: Qpid Proton
Issue Type: Bug
Affects Versions: proton-c-0.37.0
Reporter: Jiri Daněk
https://github.com/skupperproject/skupper-router/issues/125
This is likely related to
https://github.com/skupperproject/skupper-router/issues/124 and might possibly
be a Proton issue. The CI ran with Proton main branch as of today (Proton
0.37.0 rc1, pretty much).
