Reduced to:
// a.cpp
#include <vector>
struct SP {
void WeakAddRef();
void WeakRelease();
};
template <typename T> struct PtrBase {
T *volatile P;
~PtrBase() {
if (R)
R->WeakRelease();
}
PtrBase(const PtrBase &O) : R(O.R) {
if (R)
R->WeakAddRef();
}
SP *R;
bool IsValid() const { return P != nullptr; }
};
struct alignas(16) VectorSIMD4f {
float V;
};
unsigned __int64 countAF() {
class AF {
VectorSIMD4f B;
};
struct PD {
PtrBase<AF> P;
};
std::vector<PD> AFs;
unsigned __int64 C = 0;
for (auto A : AFs) {
if (A.P.IsValid())
++C;
}
return C;
}
Build with:
clang-cl a.cpp /c /O1
Please see the message just above for the cmake command to build clang.
This occurs in trunk and the 10.0 branch as well. @gchatelet Would you have a chance to take a look?
