I decided to try out the new shared stuff in 2.030 on OS X, so I ran it against
a module I've written using the -vtls flag. Now I *know* there are globals in
this module, so I was surprised to see no output.

To make doubly sure, I ran 2.030 against the example module given at
http://www.digitalmars.com/d/2.0/migrate-to-shared.html with the -vtls flag. No
output there either.

int x;

void main() {
    static int y;
}

Is the vtls flag non-functional? Is this an OS X specific issue?

I get:

dmd test -vtls
test.d(2): x is thread local
test.d(5): y is thread local

Very odd... I still get:

 cat test.d


int x;

void main() {
    static int y;
}
 dmd test -vtls


(successfully compiles with no output.)

I'm kind of at a loss as far as what else to tell you, though. I noticed also
that the help text when you run dmd without parameters makes no mention of the
new -vtls flag. Version is "Digital Mars D Compiler v2.030", again I'm on OS X
Leopard.

Oh, that's the problem. TLS isn't implemented on OSX.
