Compiler Warning (level 3) C4159

  • Artikkeli

#pragma pragma(pop,...) : has popped previously pushed identifier 'identifier'

Remarks

Your source code contains a push instruction with an identifier for a pragma followed by a pop instruction without an identifier. As a result, identifier is popped, and subsequent uses of identifier may cause unexpected behavior.

Example

To avoid this warning, give an identifier in the pop instruction. For example:

// C4159.cpp
// compile with: /W3
#pragma pack(push, f)
#pragma pack(pop)   // C4159

// using the identifier resolves the warning
// #pragma pack(pop, f)

int main()
{
}
