Bug ID: 48027
Summary: -Winvalid-constexpr fails to warn when calling
non-constexpr method on field
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org

The below should warn that y() can never be constant evaluated, but fails to as
of current trunk. Either of the following changes will restore the warning:
- Changing `void x()` to `static void x()`
- Changing `constexpr void y()` to `constexpr void y(X x)`
struct X {
void x();
};
struct Y {
X x;
constexpr void y() { x.x(); }
};
