Bug #: 51317
Summary: Wrong value category of conditional expression where
lvalue operands differ only in cv-qualification (see
DR 587)
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
GCC 4.7.0 rejects the following application of address-of operator:
int x = 1;
int const y = 2;
int const *p = &(1 ? x : y); // error: lvalue required as unary '&' operand
Such behavior was correct in C++03, but it is incorrect in C++11 - see
