gcc 4.0 gives an error message for the following file:
struct X {
void destroy_me() { X::~X(); }
};
This code is incorrect, so an error message is appropriate. However, the error
message isn't likely to be
useful.
The error message we get is:
foo.cc: In member function 'void X::destroy_me()':
foo.cc:2: error: '~X' is not a member of 'X'
But that's not the real problem. Obviously ~X() is a member of X. The real
problem is that this is the
wrong syntax for an explicit destructor invocation: the user should have
written this->X::~X(), not X::
~X() by itself.
(See the formal grammar for postfix expressions in 5.2/1, and the discussion of
pseudo-destructor
calls in 5.2.4, to see why this code is incorrect.)
