D static lib called from C on Mac OS X

Hi,

I am trying to use a D static library from C on Mac OSX Lion, but 
it always fails.

--- file mylib.d ---
module mylib;
import core.runtime;

extern(C) {
	bool mylib_init() {
		return Runtime.initialize();
	}
	
	bool mylib_free() {
		return Runtime.terminate();
	}
}
---

--- file main.c ---
extern void mylib_init();
extern void mylib_free();

int main() {
	mylib_init();
	mylib_free();
	return 0;
}
---

I am compiling using:
$ dmd -c -lib mylib.d -oflibmylib.a
$ gcc -o main main.c -L. -lmylib -lphobos2

When I run ./main, I get a EXC_BAD_ACCESS (SIGSEGV) that seems 
related to thread local storage during runtime initialization.

Am I doing something wrong or trying to do something currently 
unsupported?

Thanks,
Nicolas
