I have no idea why it would crash during the dumping process, but
I wouldn't be surprised if after a successful dump of `temacs', the=
resulting `emacs' crashes early on, since the dump will be writing
a heap which will probably contain pointers back into the code.



I haven't investigated why it = crashes in detail, but since the dumper prevents ASLR and PIE (and doesn= 9;t work on platforms such as Chromium), I think it should be replaced by a= portable dumper.=C2=A0
