<pre>My clang is 9.0.0, and the code is:
struct test { const int *addr; };
const test* setup()
{
static constexpr test atest =
{
({ static const int inner = 123; &inner; })
};
return &atest;
}
int main(){}
clang accepts it, but icc and gcc reject it.
gcc:
source>: In function 'const test* setup()':
<source>:7:22: error: 'inner' declared 'static' in 'constexpr' context
7 | ({ static const int inner = 123; &inner; })
| ^~~~~
Compiler returned: 1
icc:
source>(7): error: expression must have a constant value
({ static const int inner = 123; &inner; })
^
compilation aborted for <source> (code 2)
Compiler returned: 2</pre>
