Autoindent incorrect behaviour with macros

The auto indent function of qt creator does not work correctly with macros.

How to reproduce:

Create a header file with a macro like this:

#define TEST_MACRO(TEST_PARAM)

the macro basically does nothing, but it doenst matter. you could also have a macro that does something or just creates a semicolon like this:

#define TEST_MACRO(TEST_PARAM) \
;

Now include that header file in your cpp file and use it:

Lets assume the code is

TEST_MACRO(test)
// some comment
std::cout << "hello" << std::endl;

//comment 2

Using Ctrl+I it formats it to

TEST_MACRO(test)
// some comment
std::cout << "hello" << std::endl;

//comment 2

It is 8 white spaces too far to the right. I dont know why, but comment 2 is formatted correctly...

Edit: unfortunately you cant see the wrong white spaces in view mode... i will add a screenshot.
