This a bug report following 

http://lists.gnu.org/archive/html/help-gnu-emacs/2019-01/msg00118.html


I'm try to build emacs on Windows 10 using msys2/mingw64, and git emacs source. 
However, it raises error after dump complete.
- most updated msys2/mingw64
- Windowing system distributor 'Microsoft Corp.', version 10.0.15063
- System Description: Microsoft Windows 10 Enterprise (v10.0.1703.15063.1563)

- last success build: Repository revision: c48ea7c08c95185ddce266744a1959e0ce6b04e1  (2019-01-13)



I tried the pdumper master in last Sunday and yesterday and today with updated repository.
Current one:   94245b9a790392768d47afc15ae278369307d663



I tried make -j3 after:
- pdumper:  ./configure --without-imagemagick

- unexec:  ./configure --without-imagemagick --with-dumping=unexec



The unexec one provide clear error message:
```

The pdumper building popup a error box:

And error message:

Please run the command that fails under GDB, in the pdumper
configuration, like this:

  $ cd src
  $ gdb ./bootstrap-emacs.exe
  ...
  (gdb) run  -batch --no-site-file --no-site-lisp --eval "(setq load-prefer-newer t)" -f batch-byte-compile emacs-lisp/cconv.el

When Emacs segfaults, please type these commands:

 (gdb) thread 1
 (gdb) backtrace

and post here the results of those commands.

Thanks.

Please run the failing command in the unexec version under GDB, with a
breakpoint in wrong_type_argument; when it breaks, please show the C
and Lisp backtrace from that error message.

Thanks.
