<pre>
    We are seeing assertion errors in `llvm/lib/IR/Constants.cpp` after change https://github.com/llvm/llvm-project/commit/bbeaf2aac678633749e7385466da10a1c0120b3b was landed. The error message was:

```
clang++: llvm/lib/IR/Constants.cpp:2281: static llvm::Constant *llvm::ConstantExpr::getBitCast(llvm::Constant *, llvm::Type *, bool): Assertion `CastInst::castIsValid(Instruction::BitCast, C, DstTy) && "Invalid constantexpr bitcast!"' failed.
```

The error disappeared after this change was reverted locally.
