initialization of 'variable' is skipped by 'instruction'
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.
The following sample 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
}
