Bug #: 12117
Summary: Doesn't restrict list initializations to
standard/ellipsis conversions for copy constructor
Product: clang
Version: trunk
Platform: PC
OS/Version: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
This should be valid and call the first constructor of "B":
struct A { A(int); };
struct B { B(A); } b{{0}};
Instead, clang gives an ambiguity: "error: call to constructor of 'struct B' is
ambiguous". Clang does not implement 13.3.3.1p4 of C++11 thereby the copy and
move constructors of B would both be non-viable because they require user
defined conversions here.
