Bug ID: 63985
Summary: Accepts invalid range-based for declaration
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: R.HL at gmx dot net
int arr[] {1, 2, 3};
for (int i = 5: arr)
std::cout << i << ", ";
Compiles, while it shouldn't. A warning message suggests that GCC ignores the
loop completely.
warning: variable 'arr' set but not used
Perhaps GCC can't decide what kind of loop this is and decides to ignore it
silently?
