[llvm-dev] Fwd: buildbot failure in LLVM on sanitizer-x86_64-linux

[David Blaikie via llvm-dev]

I'm not sure how to make sense of the logs in this failure.

The sanitizer approach of using a shell script for the whole build process
seems, at least for me, to obscure what's happening/failing in the logs.
Could you help me understand how to parse these failures? (I see it's not
the only such failure recently - but without the ability to figure out the
root cause in the logs, I can't tell if they're the same/related failures
or not, and whether they're flakes or actual failures, etc)
