            Bug ID: 16627
           Summary: Behavior of __has_nothrow_constructor differs from GCC
           Product: clang
           Version: 3.2
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

Following code works well on GCC-4.6 but fails with clang 3.0 and clang 3.2:

#include <cassert>

struct nothrow_def {
    nothrow_def(int i = 0) noexcept {}
};

int main() {
    assert(__has_nothrow_constructor(nothrow_def));
}

Without `int i = 0` it work OK.
