--- Comment #4 from Kostya Serebryany <kcc at gcc dot gnu.org> --- (In reply to Dmitry Vyukov from comment #2) > It seems that this kernel has ASLR disabled, so kernel maps libraries at > 0x55. Tsan does not support this ATM. BTW, the situation with tsan's shadow became worse after http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a3defbe5c337dbc6da911f8cc49ae3cc3b49b453 where I see "Based on original patch by H.J. Lu and Josh Boyer."
