<pre>
    clang-tidy crashes while processing [nsembed.c](https://gitlab.winehq.org/wine/wine/-/blob/master/dlls/mshtml/nsembed.c) from Wine. This is the smallest example I could make that reproduces the crash:

```c
undefined1 scalar;

int array1[] = {scalar};

struct {
    int array2[sizeof(array1)];
};
```

clang-tidy only crashes on this code about 50% of the time, so if it works for you, try it several times.

```
$ clang-tidy --version
