case constant 'constant' too big for the type of the switch expression
A case constant in a switch expression does not fit in the type to which it is assigned.
Example
// C4178.cpp
// compile with: /W1
int main()
{
int i; // maximum size of unsigned long int is 4294967295
switch( i )
{
case 4294967295: // OK
break;
case 4294967296: // C4178
break;
}
