At this point, we get

```
ConditionalOperator 0x1108658e0 'int'
|-CXXBoolLiteralExpr 0x110865878 '_Bool' true
|-CXXThrowExpr 0x1108658a8 'void'
| `-IntegerLiteral 0x110865888 'int' 0
`-IntegerLiteral 0x1108658c0 'int' 0
```

nd as a result, `GetExprRange` proceeds with the throw expression (`CO->getTrueExpr()`)
