I think it's probably from a source file with nil Statements created in readJsonConfigFile:

SourceFile: (&ast.NodeFactory{}).NewSourceFile(ast.SourceFileParseOptions{FileName: fileName, Path: path}, "", nil, (&ast.NodeFactory{}).NewToken(ast.KindEndOfFile)).AsSourceFile(),

A concrete repro that yields a similar but not identical callstack:

// tsconfig.json
{ "extends": "./base.json" }
// base.json
{ "include": [1] }
