Fork Problem

[francex tiscali it]

Hi,

I have made a simple window with a button. When button is clicked popup
another window. This win includes a classic text_view. I wanna show in this
text_view a text "piped" from STDERR. For example "gcc -v" puts text in
STDERR. And so I have used:

  gint stderr_pipe;
  gchar **options;

  options [0] = "/usr/bin/gcc";
  options [1] = "-v";
  options [2] = NULL;

  ...other code...

  g_spawn_async_with_pipes (
  	NULL,
	options,
	NULL,
	G_SPAWN_STDOUT_TO_DEV_NULL,
	NULL,
	NULL,
	NULL,
	NULL, //stdin
	NULL, //stdout
	&stderr_pipe, //stderr
	NULL   );

   ...other code...

When I launch it, program crash with a "seg fault". This is strace output:
