Summary: Bogus overflow in constant expression error
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Starting with the C++ delayed folding merge, we reject this test with -fwrapv:
struct C {
static const unsigned short max = static_cast<unsigned short>((32767 * 2 +
1));
};
q.C:2:80: error: overflow in constant expression [-fpermissive]
static const unsigned short max = static_cast<unsigned short>((32767 * 2 +
1));
