> 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
> Priority: Critical
>
> 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.
