## Compiler Explorer: https://godbolt.org/z/9fE8sP7PG
- It crashed on clang `Trunk`
- generated by fuzzer

Console:

```c
typedef _Bool bool512 __attribute__((ext_vector_type(187553262)));

bool512 b;
```

Assertion:

```console
clang: /root/llvm-project/llvm/lib/IR/Type.cpp:321: static llvm::IntegerType* llvm::IntegerType::get(llvm::LLVMContext&, unsigned int): Assertion `NumBits <= MAX_INT_BITS && "bitwidth too large"' failed.
```

Backtrace:

```console
