When I use fork I am getting a core.thread.ThreadException: Unable to
load thread state exception.

This is dmd 2.047 on OS X
I am trying to convert a small C application.


module fork;
import  core.sys.posix.unistd,
        std.stdio;

void main()
{
    auto pid = fork();

    if( pid > 0 ) {
        writeln( "Parent" );
    } else if( pid == 0 ) {
        writeln( "Child" );
    } else {
        writeln( "Failed to fork!" );
    }
}


$ ./fork

I tried different flags but the output is the same.

My environment too. Please put this bug into bugzilla.
