The following code fails to compile with this error:
canonical_type_error.cpp: In function 'int A::* getmemberptr()':
canonical_type_error.cpp:8: internal compiler error: canonical types differ for
identical types int A::* and int A::*
==========================
struct A
{
int membervar;
};
typedef const A type;
int type::* getmemberptr() { return &type::membervar; }
=========================
I'm not sure if the code is valid however (using such a typedef as the class id
in a pointer to member declaration), but it did work with older builds of gcc.
It also fails if type is a template argument, which makes it possible to
stumble on this problem in a non obvious way because of automatic template
argument deduction.
