Description Andrej Mitrovic 2011-10-16 15:24:07 UTC 
import std.stdio;
__gshared Foo foo;
class Foo
{
    ~this() { writeln("Release Foo"); }
}
void main() { foo = new Foo; }

OTOH the dtor gets properly called if it's a thread-local instance.
Is this a known bug?

__gshared variables go into the data segment (.BSS), and according to the docs:
"Objects referenced from the data segment never get collected by the gc." (http://dlang.org/class.html).

TLS class objects go to the .tls section and get collected.
