In NB 8.0RC,

To test, set the formatting for C/C++ to a setting which puts openning braces on a new line, such as ANSI.
If there is a structure defined thus:

struct Structure { int a; int b; };

and initialization code is entered with braces on a new line, similar to

Structure s =
{
    2,
    3
};
, which is correct formatting according to the settings,
after formatting, it turns out like this:

Structure s ={
    2,
    3
};

, which is incorrect according to the settings.
