Compiler Warning (level 3) C4341

'value' : signed value is out of range for enum constant

An enumerated constant exceeds the limit for an int. The value of the invalid constant is undefined. Constants must resolve to integers between –4,294,967,295 and +4,294,967,295 (signed).

Note that this is a level 3 warning under /Ze and a level 1 warning under /Za.

Example

The following sample generates C4341:

// C4341.cpp
// compile with: /WX /W3 /c
enum ELEMENTS {
   Hydrogen = 1,
   Helium,
   Lithium,
   Beryllium,
   Impossibillium = 4294967296   // C4341
   // try the following line instead
   // Impossibillium = 4294967295
};

The following sample shows that C4341 is a level 1 warning under /Za

// C4341b.cpp
// compile with: /W1 /LD /Za
enum ELEMENTS
{
   Hydrogen = 1,
   Helium,
   Lithium,
   Beryllium,
   Impossibillium = 4294967296  // C4341
   // try the following line instead
   // Impossibillium = 4294967295
};
