When a class definition fails parsing in GCC’s C++ front-end, the lambda scope cleanup was not correctly handled, leading to incorrect active scope information. This commit modifies the parser to track whether a lambda scope was opened for a class head, ensuring proper cleanup regardless of the class definition’s success. This fixes PR125343.
