// On OSX this code causes a segfault. (dmd 2.063.2)
void sub() {
  import std.process;
  execute(["echo", "hello"]);
}

void main() {
  import std.concurrency;
  spawn(&sub);
}

Same thing happens with core.thread.Thread insead of std.concurrency.spawn, and
other variants like
std.process.{spawnProcess,spawnShell,pipeProcess,pipeShell}.

Works ok in linux. (2.063.2)
