(I know nothing about vi commands.) The test case constructs it "live", so after inserting the text into the buffer, point is at the end of the line. From there, "Fz" (search backwards for "z") is appropriate. My command-line example opens a file with that contents already there, and with point at the beginning of the line, so there I used "fz" search forwards for "z").

This is standard operation of the Emacs C mode: some characters,
including the left parenthesis, are "electric", in that they invoke
reindentation/reformatting of the current line. Type "C-h k (" to see
the documentation of that, including links to customization options,
which you can tweak if you don't like the default behavior.
IOW, I don't think this is a bug at all, but intended behavior.
Thanks.
P.S. Please don't cross-post to emacs-devel and the bug list.

This is a corner case.
When I start in viper mode with this file contents:
#define z_b\
and then change the "z" to a parenthesis (either one), I get this:
#define (z_b^I^I^I^I^I\$
[I have represented each TAB as "^I", of course]
Rather surprising to see all of those TAB characters inserted. To
reproduce, run this:
mkdir ~/empty && printf '#define z_b\\\n' > k.c \
&& HOME=$HOME/empty /bin/emacs -Q -f viper-mode k.c
hit "n", "n", and "5" at the successive prompts, then e.g., "fzs(" to
perform the change and to see the surprising result.
I tried to write a test case to encapsulate the above, but so far have
failed, because when run via the test, viper-mode does what one would
expect.

This is with an emacs binary I built from "master" yesterday.
Reproduce with this:
printf '%s\n' '#define abcde \\' x > k.c; emacs -q -f viper-mode k.c
Then, hit "n" at the viperize prompt and you'll see this
on the first line:
#define abcde \
Hit "W" to move the cursor to the "a". Then type "ce(" to
change the 5-byte "abcde" to a "(". I was surprised to see
the "abcde" still there, and an additional backslash appended:
#define (abcde \ \
I expected to see this:
#define ( \
