Summary: [C++0x] Non-defining declaration of deleted function
suppresses usage validation
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]

gcc 4.7.0 20110514 (experimental) in C++0x mode compiles the following program
successfully (but produces a link error):
//--
void foo() = delete;
void foo();
int main() { foo(); }
//--
It seems that the second (non-defining) declaration of the deleted function
foo() has the effect of "undeleting" the initial deleted definition. I cannot
deduce this kind of semantics from the FDIS wording: The program should be
rejected, when compiled [In a strict sense the compiler probably behaves
conforming, because in the end the program *is* ill-formed, but to me it looks
like a generally expected behaviour, that this should done by the compiler, not
by the linker. I'm hesitating to categorize this as an enhancement request and
therefore I did not so].
