Re: ./configure Make sources runs, but compiled make segfaults - is this a bug?

[Dan Kegel]

You may need this commit, which was after 4.1, if I read git history correctly:

commit 292da6f6867b75a5af7ddbb639a1feae022f438f
Author: Paul Smith <address@hidden>
Date:   Mon Oct 20 01:54:56 2014 -0400

    * main.c (main): [SV 43434] Handle NULL returns from ttyname().

Try getting the latest from git; see
http://savannah.gnu.org/git/?group=make
