Bug ID: 114609
Summary: -Waddress false positive
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: arnaud.lb at gmail dot com
Target Milestone: ---
The following code:
```
struct {
int member;
} state;
int effect;
void f(void) {
effect = ((&state)->member == 1 ? &state : 0) ? 2 : 3;
}
```
When compiled with:
```
gcc -c test.c -Waddress
```
Results in the following warning:
```
<source>: In function 'f':
<source>:8:51: warning: the address of 'state' will always evaluate as 'true'
[-Waddress]
8 | effect = ((&state)->member == 1 ? &state : 0) ? 2 : 3;
| ^
Compiler returned: 0
```
I believe this is a false positive, and no warning should be emitted.
GCC version: 13.2.1 20240316 (Red Hat 13.2.1-7)
