#include <limits.h>
char vals1[ULONG_MAX] = { // error: array is too large (18446744073709551615
elements)
};
char vals2[] = {
[ULONG_MAX-1] = 0 // no error
};
=======
The second array initialization will trigger huge memory usage (for creating
all these initializer expressions) but no error like in the constant array
case.</pre>
