    Hey there :)

I'm working on my `.clang-format`-config for a project ATM and was trying to see what effect setting `AlignArrayOfStructures` to anything other than `None`.

It appears to me that I have hit some weird edge case?

### Working example
Consider this input file:
```
// Working example of a struct-array

struct vertex {
        float position[3];
        float color[4];
        float normal[3];
};

struct vertex vertices[1] = {
        {
                { 0, 0, 0 }, { 0, 0, 0, 0 }, { 0, 0, 0 }
        },
};
```
This compiles fine with `g++ -c bug.cpp` and `clang-format --style=file --verbose bug.cpp` gives the following output:
```
Formatting bug.cpp
struct vertex {
        float position[3];
        float color[4];
        float normal[3];
};

struct vertex vertices[1] = {
        {{ 0, 0, 0 }, { 0, 0, 0, 0 }, { 0, 0, 0 }},
};
```

### Broken example
Now consider this input. Notice that I've only added a single comma inside the struct-initializer. I believe this to be perfectly fine syntax since I use it all over the place and my compiler never complains:
```
// Non-working example of a struct-array

struct vertex {
        float position[3];
        float color[4];
        float normal[3];
};

struct vertex vertices[1] = {
        {
                { 0, 0, 0 }, { 0, 0, 0, 0 }, { 0, 0, 0 },
        },
};
```
Like I said, `g++ -c bug.cpp` is perfectly happy compiling this for me. Now when I run this through `clang-format --style=file --verbose bug.cpp` I get something that's definitely not the expected output ^^:
```
Formatting bug.cpp
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.

```
Like I said previously: This happens with any value other than `None` - so either `Left` or `Right` breaks it for me.

### Additional Info
Since it told me to file a bug that is what I'm doing right now.

I'm running Arch-Linux on this ThinkPad T450s:
```
$ uname -a
Linux $(hostname) 5.16.2-arch1-1 #1 SMP PREEMPT Thu, 20 Jan 2022 16:18:29 +0000 x86_64 GNU/Linux
```

Here is some info about my `clang`-setup:
```
$ clang-format --version

        libicudata.so.70 => /usr/bin/../lib/../lib/libicudata.so.70 (0x00007f8cdb056000)
```
And my `.clang-format` (which I had to rename for uploading here): [.clang-format](https://github.com/llvm/llvm-project/files/7945400/default.clang-format.txt)

I really hope this information is useful to you! I couldn't find any report-template so I'm just winging it here...
// I also really hope this isn't something obvious like `gcc` being more permissive when really this is broken syntax.
//  Either way, I suppose, `clang-format` should be handling this more gracefully :D
