Hello, DataDog teams.
I have been facing java process crashing after update dd-agent from 1.32.0 to 1.33.0.

I guess this prevention (#84) might cause SIGSEGV.

Here is the part of changes on 1.33.0 version.
https://github.com/DataDog/java-profiler/blame/5468ef0293d175a861738b8c9624055b8c3dfc0d/ddprof-lib/src/main/cpp/objectSampler.cpp#L113

Can this frame array be referenced elsewhere after it has been deleted?

Thanks in advance.
