Bug ID: 40562
Summary: Possible miscompile with std::initializer_list after
r274385
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: l...@zaghen.it
CC: blitzrak...@gmail.com, dgre...@apple.com,
erik.pilking...@gmail.com, llvm-bugs@lists.llvm.org,
richard-l...@metafoo.co.uk
Testcase is this (also found at https://godbolt.org/z/iO4IL7 )
#include <initializer_list>
class T {
public:
int c;
T(int c) : c(c) {}
};
extern void f(std::initializer_list<T>&);
void test() {
T t(666);
std::initializer_list<T> a({t});
//std::initializer_list<T> a{{t}};
f(a);
}
Something to note is that using the commented out version will work fine.
I think both versions should be OK as "t" will still be live until the end of
the scope.
