Summary: decltype crash breaks is_constructable
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++0x
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
The following test case is reduced libc++'s is_constructable. The case causes
clang to segfault. This bug arose in a boost test case. It's hard to track down
exactly what is going on in boost, because (as always) there are many levels of
code, and clang is crashing.
struct S;
struct __any
{
__any(...);
};
template<typename T>
T& D();
template <class _Tp, class ..._Args>
decltype(D<_Args>()...)
X(_Tp&&, _Args&& ...);
template <class ..._Args>
int
X(__any, _Args&& ...);
decltype(X(D<S>(), D<int>())) j;
