Comment:

 So, this appears to be happening because madvise() is failing, which
 shouldn't be able to happen, but which might be possible.  I wonder what
 the errno value is.  My guesses would be ENOSYS or EINVAL.

 I have a possible fix in a branch `bug31570_041`.  (If the issue isn't
 fixed, it should at least have a slightly better log message.)  PR at
 https://github.com/torproject/tor/pull/1285 .

 It would be good if somebody could test this patch on an affected system,
 but I think it should be clear enough that we could try merging it anyway.
