--- 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.
