Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]

Source:
int main()
{
{
constexpr int array[1] = {0};
constexpr int i = array[0]; // OK.
}
{
constexpr int array[1] = {};
constexpr int i = array[0]; // error: array subscript out of bound. Why?
}
}
Compile errors:
a.cpp: In function 'int main()':
a.cpp:5:17: warning: unused variable 'i' [-Wunused-variable]
a.cpp:9:28: error: array subscript out of bound
a.cpp:9:17: warning: unused variable 'i' [-Wunused-variable]
Access to array[0] is valid. But, compiler says "that's an error."
