FWIW it's found at least one real bug in glibc
<https://sourceware.org/bugzilla/show_bug.cgi?id=20978> - that's a case
where strlen is called on a pointer that can never be non-null if the
strlen call is reached. (I don't know if there are other cases in glibc,
whether genuine bugs or false positives, that would appear later in the
build once that bug is fixed.)
