# If libasan isn't specified in the LD_PRELOAD path, ASAN warns about mock-ioctl
# being loaded first because its memory allocations might not get intercepted.
# But it appears this isn't a problem; ASAN errors in mock-ioctl are reported.
# This is likely because the executable still links with libasan before libc.
