Todd Lipcon created KUDU-3030: --------------------------------- Summary: Crash in tcmalloc stack unwinder Key: KUDU-3030 URL: https://issues.apache.org/jira/browse/KUDU-3030 Project: Kudu Issue Type: Bug Components: build Affects Versions: 1.11.0 Reporter: Todd Lipcon
We recently saw a crash where the tcmalloc heap profiler was trying to unwind the stack, and ended up accessing invalid memory. The issue here is that tcmalloc is relying on frame pointers for heap unwinding, but this particular stack trace was going through libstdc++, which was installed on the system and doesn't have frame pointers. "usually" this works OK, but when we get unlucky, we can crash. -- This message was sent by Atlassian Jira (v8.3.4#803005)
