The g_list_*() functions you called there work like realloc(), meaning
their return pointer may not be the same as the input one.

So I would make:

GList *foo(GList *a)
{
        a = g_list_append(a, "text");
        a = g_list_first(a);
        return(a);
}


Then in main:

> int main()
> {
>   GList *list=NULL;
>   foo(list);
>   list=g_list_first(list);
>   printf("list=%s\n", (char *) list->data);
>   return 0;
> }

Change that to:

int main()
{
        GList *list = NULL, *next;

        list = foo(list);
/*      list = g_list_first(list); */

        next = list;
        while(next != NULL)
        {
            printf("list = %s\n", (char *)next->data);
            next = next->next;
        }

        return(0);
}
