<pre>The code is as follow:
namespace std
{
struct string
{
~string();
string();
};
}
int
main(const int,
const char * const * const)
{
std::string x[0UL][0UL] =
{
};
std::string y[0UL] =
{
};
int z[0ul][0UL] =
{
};
return 0;
}
It comes from a gcc bug report:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=35602">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=35602</a>
Indeed, a previous version of g++ produces a different warning message, but
users are not satisfied. As a result, g++ generates a new warning message.
However, clang++ accepts it without any warnings. Shall clang also add some
warning messages for this?</pre>
