Hi Max, I'm aware of this issue because it was reported by someone else. Sadly
I wasn't able to install that toolchain on my centos machine (I don't manage
it) so I can't reproduce the issue to make sure I can fix it. This issue
doesn't happen with other toolchains.
So, I would like to ask for your help to try to fix it. I think the fix might
be something as simple as doing
return std::move(trace)
or perhaps something like
return
Expected<std::unique_ptr<IntelPTPerThreadProcessTrace>>(std::move(trace));
At this point I can only rely on you to make sure this is properly fixed
