this is causing a crash with precompiled headers. I can try to reduce, but hopefully the problem is obvious from this assert/stack trace?
```
clang++: ../../llvm/include/llvm/ADT/SmallVector.h:295: const_reference llvm::SmallVectorTemplateCommon<std::unique_ptr<clang::serialization::ModuleFile>>::operator[](size_type) const [T = std::unique_ptr<clang::serialization::ModuleFile>]: Assertion `idx < size()' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
