Oh, sorry, your are right, the example indeed works.
BUT: I used in fact a slightly different example
(sorry, didn't expect that there is a difference):
int main() {
int i = 0;
int j = i++ << i++;

AFAIK, since C++17 we should be able to do:

C++17 is based on C11, which now standardizes aligned_alloc().
However, does not provide it under namespace std:
#include
int main()
{
auto p1 = std::malloc(100); // OK

The following C++17 program should not compile, but it does:
#include
int main()
{
auto d = 42;
if constexpr (d > 0) {
std::cout << "oops \n";
}

It seems for a template the type of N is ignored if the value

OK, thanks for the discussion and especially for the FAQ entry.
I still find it a bit unfortunate that clang and VC++ give an error

Sorry, but IMO this is NOT the same.

which is already supported by C.

Thanks a lot, Paolo and Dave.
The explanation makes total sense to me and putting gcc 4.5.0
in front of the path fixes the problem.

compiling with -static also fixes the problem, which also supports
the theory of using wrong DLL's.
The only question is, why are the wrong libs used without -static.
Any idea?
