Compiler Warning (level 1) C4533

initialization of 'variable' is skipped by 'instruction'

Remarks

An instruction in your program changed the flow of control, so an instruction that initialized a variable wasn't executed.

The /sdl (Enable Additional Security Checks) compiler option elevates this warning to an error.

Example

The following example generates C4533. To resolve the issue, move the initialization before the jump instruction or after the target of the jump.

// C4533.cpp
// compile with: /W1
#include <stdio.h>

struct A
{
   int m_data;
};

int main()
{
   if (1)
   {
      goto Label;
   }

   A a = { 100 };

   Label:   // C4533
      printf("\n%d", a.m_data);   // prints an uninitialized value
}
