<pre>Consider the following well-formed program (prog.cc):
#include <limits>
enum E { x = std::numeric_limits<long long int>::max(), y };
int main() {}
Compile it with the following command line:
clang++ prog.cc -stdlib=libc++ -std=c++14 -pedantic-errors
The enumerators x and y fits in unsigned long long int, but clang incorrectly
gives the following error message:
prog.cc:2:57: error: incremented enumerator value 9223372036854775808 is not
representable in the largest integer type [-Werror,-Wenum-too-large]
enum E { x = std::numeric_limits<long long int>::max(), y };
^
