           Summary: writeln crashes when called from C code.
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Mac OS X
            Status: NEW
          Severity: major
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: kennytm gmail.com



Given the following content:

  // x.d
  import std.stdio;
  extern (C) void foo() {
      writeln("1");
  }

  // y.c
  void foo(void);
  int main () {
      foo();
      return 0;
  }

And compile and run with

  gcc -c -m32 y.c -o y.o
  dmd x.d y.o -ofx
  ./x

Result in a Bus Error on Mac OS X. (I am using dmd r620, druntime r370 and
Phobos r1900.)

When calling from C you have to explicitly initialize D's runtime first. Your
program calls Phobos function on uninitialized druntime and will obviously
crash.
