GCC now correctly throws an exception in the extract_ref function, a part of the C++ reflection implementation, when it encounters invalid array types (e.g., arrays of functions or methods). Previously, the code attempted to build arrays of these invalid types, leading to internal compiler errors (ICE). This fix ensures that the appropriate exception is thrown, providing more robust error handling during reflection.
