Bug ID: 80458
Summary: [-Wreturn-type] false negative on missing return
statement in a member function
Product: gcc
Version: 7.0.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: skvadrik at gmail dot com
Target Milestone: ---
On the following example (missing return statement in a member function) GCC
emits no warning:
$ cat 1.cc
#include <stdlib.h> // exit
extern void *f();
class Bag {
void *g() {
void *p = f();
if (!p) exit(1);
}
};
$ g++ -c -Wall -Wextra -O2 1.cc
$
If I comment out class definition, GCC emits warning:
$ cat 1.cc
#include <stdlib.h> // exit
extern void *f();
//class Bag {
void *g() {
void *p = f();
if (!p) exit(1);
}
//};
$ g++ -c -Wall -Wextra -O2 1.cc
1.cc: In function ‘void* g()’:
1.cc:7:5: warning: control reaches end of non-void function [-Wreturn-type]
}
