For function parameters that are subject to "pointer decay", the database contains the type as originally declared (e.g. `T[]` instead of `T*`). The IR needs the actual type. Similarly, for variable declared as an array of unknown size, the actual size needs to be inferred from the initializer (e.g. `char a[] = "blah";` needs to have the type `char[5]`). I've opened a ticket to have the extractor emit the actual type alongside the declared type, but for now, this workaround is enough to unblock progress for typical code.
