--- Comment #2 from seurer at gcc dot gnu.org ---
I looked through the various patches for the sanitizer stuff and the important
one that is missing is the one that disables ASLR when the sanitizers are in
use.  This would "solve" the issue where the thread sanitizer tests fail
depending on how ASLR has laid out memory (something I see all the time with
gcc-8 and recent kernels).

However, the thing that prompted this bug report

https://github.com/openbmc/openbmc-build-scripts/commit/282e33011ea62fe80bff2c5ab0e9ef9446d6c551

is dealing with the *address* sanitizer and I haven't seen that sort of
problem.  It looks like it occurs when they are building openbmc which I have
never done.
