llvm dev - Aug 2021 - FW: LLDB Incremental - Build # 34308 - Failure!

Hi forks,

I received below failure after I submitted D105263. I’m confused about the
report since it tells no failure in the summary but did turn from green to red.
I skimmed the 3 log files and found they are pointing to the same lit fail[1].
Unfortunately, I can’t reproduce it locally due to it requires a Darwin system.
Do you know if there’s a way to reproduce it on a Linux system? Or anyone who
can help with this issue? I know nothing about llgdb and what it is testing
here.
Any comments are appreciated.

From the commit logs, I doubt this is caused by your changes.

Jonas, Adrian, do you know if this is a flaky debug info test?

Cheers,
Florian
