Description
In qhashfunctions.h the code reads as
Q_DECL_CONST_FUNCTION inline uint qHash(std::nullptr_t, uint seed = 0) Q_DECL_NOTHROW
{
return qHash(reinterpret_cast<quintptr>(nullptr), seed);
}
but reinterpret_cast<quintptr> cannot be used to cast from a nullptr. It probably should be changed into something like
Q_DECL_CONST_FUNCTION inline uint qHash(std::nullptr_t, uint seed = 0) Q_DECL_NOTHROW
{
void* ptr = nullptr;
return qHash(reinterpret_cast<quintptr>(ptr), seed);
}
The current implementation results in a compiler error with the v140 Toolchain of Visual Studio.
