Here's a sample (die.d) that used to work some time ago:

  void main() {
    Object foo = null;
    auto b = foo.toUtf8;
  }

You need dmd 1.0xx (1.016 - 1.018 at least cause this) + tango (I'm using the
svn version). You also need to use -g switch.

$ dmd -g die.d
gcc die.o -o die -g -m32 -Xlinker -L/home/jm/d/dsss/lib -lphobos -lpthread -lm

$ gdb die
