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.
