The problem is here:

ptr = val;

Then both ptr and val will point to the same address, and you are a double free/delete on the same address.

I will try illustrate what's happening, let's assume 32bit addresses:

int main()
{   
    const int* ptr = new int();      // ptr allocate 4 bytes @ heap
                                     // for illustration purposes
                                     // ptr is @ address 0x80000010
    int* val=new int();              // val allocate 4 bytes @ heap
                                     // val is @ address 0x80000020
    ptr = val;                       // now ptr is @ address 0x80000020   
    std::cout << *val << std::endl;  // print out the int @ address 0x80000020   
    delete val;                      // free memory @ 0x80000020
    delete ptr;                      // free memory @ 0x80000020 - this will result in a double-free, 
                                     // no good, program will most likely crash
    
    return 0;
}  

NOTE: address 0x80000010 and 0x80000020 are just for example illustration, running this application for real the allocated addresses on heap will most likely be completely different.
