    Hello,
Im using LLVM lib release 13.0.0 and im parsing c++ files using `buildASTfromCodeWithArgs `method.
When im trying to parse one certain file with passed argument `-std=c++17` it throws stack overflow exception

When im using argument `-std=c++14 ` or `-std=c++11` the problem goes away and it works fine. 
Also when I dont use this argument problem does not exist too.

The file im trying to parse contains only include to another file and some defines.

Thats code for executing `buildASTFromCodeWithArgs ` method:
```
std::unique_ptr<clang::ASTUnit> ast{
         clang::tooling::buildASTFromCodeWithArgs(fileContent, args, file, "clang++",
                                                  std::make_shared<PCHContainerOperations>(),
                                                  tooling::getClangStripDependencyFileAdjuster(),
                                                  tooling::FileContentMappings(),
                                                  diagnosticConsumer)
      };
```

where fileContent is files text, args is as I said `"-std=c++17"`, file is path to file.
