<pre>The following code
```
int foo {[]() {
int bar{ 0 };
return 0;
}()};
```
is formatted into
```
int foo{ []() {
intbar{ 0 };
return 0;
}() };
```
by clang-format-9 when using -style="{AlignConsecutiveDeclarations: true,
Cpp11BracedListStyle: false}".
The resulting code no longer compiles - note the missing space between `int`
and the variable name.
Changing either formatting option will fix the problem, it's the combination
that leads to the erroneous output.
The code is also correctly formatted if the outer braces (initialization of
foo) are replaced by a `=` assignment.
I don't have a later clang-format version than 9 installed locally, but trying
this code snippet in <a href="https://zed0.co.uk/clang-format-configurator">https://zed0.co.uk/clang-format-configurator</a> with
10.0.0+b452de0 and these two formatting options, the output suddenly gets blank
(-> crash?).</pre>
