Bug ID: 113687
Summary: -Warray-bounds is not emitted inside class method
Product: gcc
Version: 13.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nmmm at nmmm dot nu
Target Milestone: ---
No warning -Warray-bounds is shown when code is inside class method, defined
inside the class body or outside if they are inline or constexpr.
struct S{
int p(){
int x[2] = {0, 0};
return x[3]; // no warning shown
}
static int ps(){
int x[2] = {0, 0};
return x[3]; // no warning shown
}
int ps2inl();
int ps2();
};
inline int S::ps2inl(){
int x[2] = {0, 0};
return x[3]; // no warning shown
}
int S::ps2(){
int x[2] = {0, 0};
return x[3]; // warning shown correctly
}
int f(){
int x[2] = {0, 0};
return x[3]; // warning shown correctly
}
int main(){
}

Yeah, we try to avoid diagnosing things on "dead" code and here the whole functions are dead. IIRC even -fanalyzer runs after cgraph removes unreachable functions. It would be still nice to diagnose these kind of trivial cases.
