On MSYS2 64bit build from trunk and emacs-25 branch, emacs hangs when
w32-shell-execute is called with "open" operation (no CPU usage, but
not respond to C-g).

(w32-shell-execute "open" "D:/test.pdf")

The bevhavior seems to depend on target.  For example, "a shortcut for
'Cygwin Terminal'" has no problem, but "cmd.exe" hangs emacs and
cmd.exe is not executed.  Overmore, Cygwin build (both 32bit and
64bit) from the same source has no problem.

I cannot reproduce this in a 32-bit build: I see no problem with
w32-shell-execute and PDF targets (or any other target I tried).

Can you step with a debugger into w32-shell-execute, and see where it
hangs?

Can you show all the usual information about the affected build,
everything that's collected by 'report-emacs-bug'?  It might be
important (and should be part of a bug report anyway).

Thanks.

I cannot reproduce in Emacs 25.1.50.1 x86_64-w64-mingw32 running on
Windows 8.1 64bits. The pdf opens correctly and trying to open a file
with an unregistered extension pops up the Windows dialog for choosing
an application for opening it.

Thanks.  I suspect the original problem has something to do with local
setup on the OP's system.

Sorry for insufficient infromation.  And I noticed the problem is due
to my local patch.  I mistook the result of patched trunk for emacs-25
branch which is not patched.  The patch was disabled on Cygwin build
and did not affect.

I'm closing it.  Sorry for my mistake.
