Subject: #BUG ABOUT EMACS# not support compilation as PIE
Date: Thu, 5 Sep 2019 11:43:49 +0000

[Message part 1 (text/plain, inline)]
Emacs  24.3 (gnu/linux, x86_64)

Question1: Why emacs do not have fPIE(Position Independent Executable)?

Question2: I try to compile as a positon-independent executable, modify src/Makefile  with adding CFLAGS=-fPIE  LDFLAGS=-pie
                   Then I make and get Emacs segfaults when dumping.
