The man page people disagree with you - I already asked them:

  http://www.spinics.net/lists/linux-man/msg09067.html

(That's how I got here.) They claim that the glibc manual does not
imply anything. Perhaps they were looking in the wrong place?
Here is the link they were looking at:

  https://www.gnu.org/software/libc/manual/html_node/Dynamic-Output.html

That link clearly says nothing about *strp on failure.

Is there a different specification they are supposed to be
working from that you have in mind?
