AFAIK, on posix you should join the child thread, and when you do, the stored exception is rethrown in the joining thread.

Thanks all.
I gues I must rewrote my app to send exeptions to other threads, use non blocking io, etc, etc.

Hm... what about:

import std.traits: Parameters;

auto mySpawn(F)(F func, Parameters!F params)
{
    static auto callIt(F func, Parameters!F params)
    {
        try
        {
            return func(params);
        }
        catch(Throwable t)
        {
            // print the exception/error, e.g.:
            import std.writeln;
            writeln(e.toString());
            // terminate program
            import core.stdc.stdlib : exit;
            exit(1);
        }
    }

    return spawn(&callIt, func, params);
}

void main()
{
    auto tID = mySpawn(&func);
    ...
}

Main thread still running.

Actually it's depends on compiler.
With ldc2 main thread doesn't stop, but with dmd seems all ok:
root@proxytest:~# ./newthread
object.Exception@newthread.d(30): Everything is bad.

Maybe it's helps me.

I found the solution which works with dmd and ldc2:

...
import core.stdc.stdlib: _Exit;
_Exit(exitcode);
...
