Bug ID: 51057
Summary: False negative -Wreturn-stack-address when returning
std::function instead of auto
Product: new-bugs
Version: 12.0
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: josephcsi...@gmail.com
CC: htmldevelo...@gmail.com, llvm-bugs@lists.llvm.org
Consider this C++ code:
#include <functional>
struct Foo {
void bar();
};
auto f() {
Foo foo;
return [&]() {
foo.bar();
};
}
It results in a -Wreturn-stack-address warning, as it should. But if you
replace "auto f()" with "std::function<void()> f()", then the warning goes
away, even though the problem is still there.
