Summary: warn_unused_result attribute ignored for templates
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ian@airs.com
When I compile this C++ code with current mainline
class C {
public:
template<typename T> bool f(T* m) __attribute__((warn_unused_result));
};
template<typename T> inline bool C::f(T* m) { return true; }
void f(C* pc) { int i; pc->f(&i); }
I should see a warning for the call to pc->f. However, I see no warnings.
I do see a warning for a member function which is not a template.
