--- Comment #6 from Maxim Ostapenko <chefmax at gcc dot gnu.org> ---
Ok, it seems that libasan calls some function to be intercepted while
AsanInitInternal still not completed. Could you try to run memcmp-1.exe under
gdb to provide a backtrace from failed CHECK? This way, we'll probably can
figure out what function was intercepted.
