Is there any possibility how to suppress dumping emacs?
Shall I add something to ./configure script or even to make?

Greetings

It seems that this code is also incompatible with PIE.

Together with our binutils-2.23.52.0.1-54 (https://bugzilla.redhat.com/show_bug.cgi?id=1247126)
it segfaults each time. Now.
What do you think about it?

Nowadays I have commented out the code mentioned on line
http://git.savannah.gnu.org/cgit/emacs.git/tree/src/unexelf.c?h=emacs-24#n869
and afterwards is fails with
