The warning could have prevented the bug fixed in https://github.com/llvm/llvm-project/pull/165056.
This is a proposal for a new diagnostic that could detect possibly unintended calls to pointer overloads when a value overload also exists.
Consider the following code:
```
void foo(int);
void foo(int*);
void test() {
int x = 123;
int *p = &x;
foo(p); // probably intended: foo(*p);
}
```
This code is valid and unambiguous. However, in some situations, this pattern reflects a common user mistake: the programmer meant to dereference the pointer but forgot the `*`.
