[Message part 3 (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.

Patrick

Version: 27.1

>> ... it should be replaced by a portable dumper.

And lo, it was.

Compiling with -fPIE seems to work with the portable dumper that will be
the default for Emacs 27.1 onwards.
