[note: this was also mentioned in
http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D.learn&article_id=35199
but I didn't see a bug report; I'm also adding that the code worked fine in
2.058 ]

calling D runtime initialization from C fails on OSX in 2.059, but it worked in
2.058. This is a critical bug as it makes it now impossible to call D from C on
OSX.

//main.c
extern void mylib_init();
extern void mylib_free();
int main() {
        mylib_init(); //crashes here
        mylib_free();
        return 0;
}

//mylib.d
module mylib;
import core.runtime;
extern(C) {
        bool mylib_init() { return Runtime.initialize();}        
        bool mylib_free() { return Runtime.terminate();}
}


//Makefile
all:
    dmd -c -lib mylib.d -oflibmylib.a
    gcc -o main main.c -L. -lmylib -L/usr/share/dmd/lib -lphobos2

//output: (through gdb):
