[Message part 3 (message/rfc822, inline)]
emacs-27.0.50_2019-01-17 built with following configuration dumps core
(segmentaion fault), when `-nw' option is specified.
When built it with `--with-pdumper=no --with-dumping=unexec'
configuration options, it works fine with `-nw' option.
I suspected the reinitialization after loading a pdmp file is
inadequate, and found the next patch fixes the problem.
