Summary: gcc doesn't accept null pointer value as a template
non-type argument
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: boostcpp@gmail.com
According to 14.3.2 [temp.arg.nontype],
a constant expression that evaluates to a null pointer or null member pointer
value can be a template argument.
Thus, following code is well-formed.
But gcc issues errors.
template < void * ptr >
struct X { } ;
int main()
{
X< 0 > x1 ; // error: could not convert template argument '0' to 'void*'
X< nullptr > x2 ; // error: could not convert template argument 'nullptr'
to 'void*'
}

I think this is a dup of PR 10541
