returning address of local variable or temporary
A function returns the address of a local variable or temporary object. Local variables and temporary objects are destroyed when a function returns, so the address returned is not valid.
Redesign the function so that it does not return the address of a local object.
The following sample generates C4172:
// C4172.cpp
// compile with: /W1 /LD
float f = 10;
const double& bar() {
// try the following line instead
// const float& bar() {
return f; // C4172
