I don't understand the question.  Are you asking why shared_ptr hasn't
been used in GCC before?  Surely that's obvious, the GCC code is still
written in C and no C++ templates have been introduced to the code

Maybe shared_ptr isn't the right tool for memory management in GCC,
but if it's rejected then I hope it will be for valid reasons, not
because of misinformation about being unsuitable for code with
circular references.
