  Log Message:
  -----------
  [libc] __stack_chk_fail post submit test failures (#75962)

Use a size smaller than the smallest supported page size so that we
don't
clobber over any guard pages, which may result in a segfault before
__stack_chk_fail can be called.

Also, move __stack_chk_fail outside of our namespace.
