[gtkmm] Trouble spawning a process

[Quan Nguyen <friday_morning yahoo com>]

I'm new to GTK, and I am having trouble spawning a
process.  I'm getting this error "abnormal program
termination" when I use the following code.  Can
anyone tell me what I'm doing wrong? 

I'm using Windows with GTK 2.2.4.1  and GTKMM 2.2.8.1.
 Everything is installed correctly since I'm able to
compile GTKMM apps successfully.  I just want to be
able to fork processes in a cross-platform way using
GLIB.  The documentation for forking processes in GLIB
is sparse.

----------- below is code --------------

string filename="helloworld.exe",
path="D:\\Dev-Cpp\\projects\\";

  vector<string> filename_arg, env_arg;

  filename_arg.push_back(filename);
  env_arg.push_back(path);

  Glib::spawn_async_with_pipes("", filename_arg);
