Bug #: 12690
Summary: Friend field access in default template parameter
Product: clang
Version: trunk
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
In the following code, C accesses A's field in the template parameter instanced
from B. G++ and Visual C++ both allow this if B is a friend of A. Clang does
not. I don't know what is the desired behavior here, but it's inconsistent with
other compilers at least.
template<class T, int T::*field = &T::field> class C
{
};
class A
{
int field;
friend class B;
};
class B
{
C<A> field;
};
