--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- The following types I don't have a fix for yet: __sanitizer_shmid_ds __sanitizer___kernel_fd_set __sanitizer_sigset_t/__sanitizer_kernel_sigset_t __sanitizer_kernel_sigaction_t Really I think sanitizer should be auto-generating this header rather than having its own copy.
