llvm dev - Jul 2017 - libfuzzer tests on Linux

Hi,

A couple of LibFuzzer tests are consistently failing for me on Linux with
top-of-trunk LLVM/Clang/compiler-rt.
These same tests work under mac os.
I'm exactly reproducing the commands from the CI to do a two-stage build
(http://lab.llvm.org:8080/green/job/libFuzzer).

Moreover, looking at CI further it seems that it is running on a macbook: so
could it be that tests are actually failing?

Thanks,
George

Update:

I was obviously looking at the wrong CI, the proper URL is
http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer/builds/6489/steps/stage2%2Fasan%2Bassertions%20check-fuzzer/logs/stdio

However, for me tests are still failing, *unless* I explicitly build
"llvm-symbolizer” before running “ninja check-fuzzer”.
I strongly suspect that the CI machine just has llvm-symbolizer already
installed in $PATH, and that’s why the tests succeed.
