OK, the reason when I recompile Make 4.1 (without any changes) and then it
immediately segfaults on my system is this:
in the file main.c on line 1404:
define_variable_cname ("MAKE_TERMOUT", TTYNAME (fileno (stdout)),
o_default, 0)->export = v_export;
this is a macro that expands to :
define_variable_in_set(("MAKE_TERMOUT"),(sizeof ("MAKE_TERMOUT") - 1),(ttyname
(fileno (stdout))),(o_default),(0), current_variable_set_list->set,((gmk_floc
*)0)) ->export = v_export;
and here, the argument
(ttyname (fileno (stdout))) has value 0
then this is expected to be a string that later that gets passed to xstrdup and
that segfaults.

Subject: Re: ./configure Make sources runs, but compiled make segfaults - is
this a bug?
Mark,
I guess that maybe in your chroot you don't have gdb or strace or
valgrind or whatever?
Does your build of make crash when run outside the chroot? If it
does then you might be able to get it into a more normal situation.
Dan's idea about using ldd and checking the help are good too as they
might indicate where things are going wrong without needing any
special tools.
Regards,
Tim
