While creating a constructor for my class, I have a multiline
initializer list. For the constructor, the indentation matches that of
the list. Here's an example:
Test::Test(const std::string &a) : a{a}, b{0},
c{"..."}, d{""} {
/*notice the indentation*/ }

Would you please be explicit about what is wrong with the indentation.
Is it the position of the closing brace on line 3, or the indentation of
"c{" on line 2, or something else?
Thanks!

Hello Alan,
It is the position of the closing brace on the third line.
Thank you.

Hello again, Richard.

OK. Thanks for reporting this bug!
The problem is a low level CC Mode routine, c-beginning-of-statement-1
(which does what it says) starting at the last open brace on line 2 was
only going back as far as the d of d{""}, being confused by the
initialiser list's brace blocks into thinking that a new statement began
there.
Would you please apply the following patch to your Emacs-25.2 (Note: this
patch likely won't apply cleanly to later versions of Emacs), to the file
...../emacs/lisp/progmodes/cc-engine.el. Then please byte compile that
file and try it out with your real source code. (If you want any help
applying the patch or byte compiling, feel free to send me private
email.) Finally, please confirm to me that the bug is fixed, or tell me
what's still wrong.
The plan is then to install the fix into the Emacs master and emacs-26
branch.
Thanks!
