I cannot reproduce this.  I tried on GNU/Linux and on MS-Windows, and
I get the expected results on each one of them.

I also wonder where did that icomplete-post-command-hook come from in
"emacs -Q".  Icomplete mode is supposed to be disabled in "emacs -Q".

I imagine this is fixed on master by 109a3bf6a1.
(ie, a duplicate of bug#6997).

Ah, yes.  Then we should close this, I think.

Copied from mail in emacs-devel to make this clear:

Note:
The error message is not right in the original mail. That error message
was copied from another emacs session( not "emacs -Q"). The error
message in this mail(in the step 4) is the right one. Sorry for the mistake.

I just pull the latest version from emacs git repo, and run "git clean 
-f -x -d" to clean up. Then config with command:

CFLAG=-O2 ./configure --prefix=/home/jun/apps/emacs-26 
--without-makeinfo --with-x-toolkit=gtk3 --with-modules

and make with command:
make && make install

The problem still exists.

In step 3, it seems that ONLY THE FIRST tab key produce the error 
message for a emacs instance. Pressing the tab key twice, it will show 
the completion window with content as following:

------------------------------------------------------------------
Click on a completion to select it.
In this buffer, type RET to select the completion near point.

Possible completions are:
w32-check-shell-configuration 	w32-convert-standard-filename
w32-get-valid-locale-ids 	w32-list-locales
w32-set-default-process-coding-system 	w32-set-system-coding-system
w32-shell-dos-semantics 	w32-shell-name
w32-system-shell-p

-------------------------------------------------

Why these symbols are visible on GNU/Linux? Is there something wrong 
with my build commands?

It is fixed on master, not on emacs-26. Can you backport it to emacs-26?

No, it's too extensive, and the problem itself is not important
enough, I think (why would a GNU/Linux user want to display help on
Windows-specific features?).  The emacs-26 branch is for fixing bugs
that are either serious/urgent or which were caused by recent
regressions.

OK. No perfect product. I can stay with it.

But how to prevent others to report same bug? The easy way may be fixing 
it. :)

We did fix it: on the master branch.

FWIW, while I see the reported error with net junes recipt with
emacs-26.1 on linux (an older SuSE) ...

... I can't confirm this. A just freshly build emacs-27.0.50.2 doesn't
raise error for me on the same box with the recipt.

In my tests, the first TAB already brings up the completion you describe
(and doesn't signal any error).

Because these are functions defined in Elisp files available in
load-path, so they can be loaded (and you can subsequently call them)
even on GNU/Linux (at that point, they likely won't work as expected
because their implementation depends on underlying features only
provided by the w32 part of the C code).

In some unlikely hypothetical future, they could even be useful if we
can manage to build a GNU/Linux version of Emacs which links with Wine
to display w32 frames.

No,
