Description

We're getting lots of warnings like the ones below from valarray tests. Even four levels of inlining in user code (not at all uncommon) triggers the noise...

$ cat t.cpp && make t
#include <valarray>

inline void f0 (std::valarray<int>) { }
inline void f1 (std::valarray<int> va)

{ f0 (va); }

inline void f2 (std::valarray<int> va)

{ f1 (va); }

inline void f3 (std::valarray<int> va)

{ f2 (va); }

inline void f4 (std::valarray<int> va)

{ f3 (va); }

int main ()
{
f4 (std::valarray<int>());
}
