[GitHub] [trafficserver] linnaea commented on issue #5117: failed test: test_Logutils2 (in docker container)
linnaea commented on issue #5117:
URL: https://github.com/apache/trafficserver/issues/5117#issuecomment-778644537
This seems like a more run-of-the-mill memory corruption, got SEGV when packaging but cannot reproduce on my local machine.
However running valgrind locally gives this trace:

And a bunch of other errors when exiting.
Running gdb in the packaging container gives this backtrace:

Also it seems to be reproducible without running any test in LogUtils2:
