Hello,
After a quick search in forum it seems nobody have ride up this probleme yet.
In version 14609, function :
template <class T>
inline hash_t GetHashValue(const T& x) { return x.GetHashValue(); }
Raise error on compilation on MSVS19 and Clang.
I have made a quick test case :
#include <Core/Core.h>
using namespace Upp;
CONSOLE_APP_MAIN
{
ArrayMap<float, int> MyMap ={{8.02f,45},{4.85f,52},{1.75f,12},{9.36f,1},{6.04f,71}};
}
PS: It seems this post is not in is right forum category, I'm sorry, I don't know how could I move it

The problem appears to be in Topt.h where there is no specialization for float (line 476):
//template<> inline hash_t GetHashValue(const float& a) { double memhash(&a, sizeof(a)); }
is commented out but it clearly has an error in it. It should be
template<> inline hash_t GetHashValue(const float& a) { return memhash(&a, sizeof(a)); }
After making that change it appears to work.
