It is what the Linux man page says for kill()
```
KILL(2)
Linux Programmer's Manual
KILL(2)
NAME
kill - send signal to a process
SYNOPSIS
#include <sys/types.h>
#include <signal.h>
```
Actually Darwin/macOS (and presumably FreeBSD) only needs signal.h

Just a standard “hello world” but compiled and linked with the coarray shmem lib
(i.e. the code does no coarray work at all)
FWIW I tried one of Thomas’ coarray examples and it behaves the same - hangs in
the startup.

Unfortunately, as soon as I try to run it under a debugger - the hang
disappears .. as a hunch I’d look for a potential race condition in the startup
code ..

Maybe FX will be able to help - but I think he’s very busy too.
