Hi,

Thanks for reaching out to us.

We are forwarding this issue to the concerned team.

Thank you.

How did you compile the code with icpc/g++? Any #include header files or command line options I need to have?

$ icpc -c 04801613.cpp

04801613.cpp(5): error: identifier "__builtin_coro_done" is undefined

 bool d = __builtin_coro_done (co_h);

      ^

$ cat 04801613.cpp

int main ()

{

void *co_h;

bool d = __builtin_coro_done (co_h);

}

Regardless, the compiler should emit an error and terminates normally instead of given a core dump.

I've reported this problem to our Developer.

Thanks,
