Given a C++ file with following content
```cpp
struct S {
int a;
int b;
};
int aaa(S s);
int bbbb(S s);
namespace f {
int a(S s);
int bb(S s);
} // namespace f
int main() {
auto a = S{ 1, 2 };
aaa({ 1, 2 });
bbbb({ 1, 2 });
f::a({ 1, 2 });
f::bb({ 1, 2 });
aaa({
1,
2,
});
auto i = aaa({
.a = 1,
.b = 2,
});
bbbb({
1,
2,
});
auto j = bbbb({
.a = 1,
.b = 2,
});
f::a({
1,
2,
});
auto k = f::a({
.a = 1,
.b = 2,
});
f::bb({
1,
2,
});
auto l = f::bb({
.a = 1,
.b = 2,
});
}
```
when it is formatted using clang-format (20.1.2) with the following config file,
```yml
AlignAfterOpenBracket: BlockIndent
Cpp11BracedListStyle: false
```
the result of the formatting is inconsistent:
```cpp
struct S {
int a;
int b;
};
int aaa(S s);
int bbbb(S s);
namespace f {
int a(S s);
int bb(S s);
} // namespace f
int main() {
auto a = S{ 1, 2 };
aaa({ 1, 2 });
bbbb({ 1, 2 });
f::a({ 1, 2 });
f::bb({ 1, 2 });
aaa({
1,
2,
});
auto i =
aaa({
.a = 1,
.b = 2,
});
bbbb(
{
1,
2,
}
);
auto j = bbbb(
{
.a = 1,
.b = 2,
}
);
f::a(
{
1,
2,
}
);
auto k = f::a(
{
.a = 1,
.b = 2,
}
);
f::bb(
{
1,
2,
}
);
auto l = f::bb(
{
.a = 1,
.b = 2,
}
);
}
```
The bug only happen specifically when setting `AlignAfterOpenBracket` to `BlockIndent` and `Cpp11BracedListStyle` to false, also happen when setting `AlignAfterOpenBracket` to `AlwaysBreak` and `Cpp11BracedListStyle` to false, though the result is different:
```cpp
struct S {
int a;
int b;
};
int aa(S s);
int bbbb(S s);
namespace f {
int a(S s);
int bb(S s);
} // namespace f
int main() {
auto a = S{ 1, 2 };
aa({ 1, 2 });
bbbb({ 1, 2 });
f::a({ 1, 2 });
f::bb({ 1, 2 });
aa({
1,
2,
});
auto i =
aa({
.a = 1,
.b = 2,
});
bbbb(
{
1,
2,
});
auto j = bbbb(
{
.a = 1,
.b = 2,
});
f::a(
{
1,
2,
});
auto k = f::a(
{
.a = 1,
.b = 2,
});
f::bb(
{
1,
2,
});
auto l = f::bb(
{
.a = 1,
.b = 2,
});
}
```
The expected result should be the same as the input.
Tested on clang-format 20.1.2 (Fedora 20.1.2-3.fc42)
