Bug ID: 60753
Summary: defining an explicit function template specialization
as deleted, following a non-deleted declaration, not
diagnosted
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: filip.roseen at gmail dot com

testcase.cpp
template<class T> void func (T);
template<> void func<int> (int);
template<> void func<int> (int) = delete;
int main () { }
------------------------------------------------------------------------
`gcc` accepts the above snippet.
------------------------------------------------------------------------
The previous snippet is ill-formed according to [dcl.fct.def.delete]p4:
> A deleted definition of a function shall be the first declaration
> of the function or, for an explicit specialization of a function
> template, the first declaration of that specialization.
------------------------------------------------------------------------
`clang` correctly issues the following diagnostic:
testcase.cpp:4:35: error: deleted definition must be first declaration
template<> void func<int> (int) = delete;
^
testcase.cpp:3:17: note: previous declaration is here
template<> void func<int> (int);
^
