HELP:glist hogging memory [BUG?]

[Javier Terradas <terry ati es>]

Hi, 
I'm stuck with a glist problem. Whenever I put something in a list data I
can't free its memory, I receive no error but the memory gets lots. I've
read the docs and I'm completely stuck with this one.

Here I put one of the tests I've tried. I fill a dynamically generated
array. With no options it just gets freed without problem (output 1), 
but if I put the data in a list it never gets freed (output 2). Here is
the test program and the output it generates.

Please help.

#include <stdlib.h>

void create_list(gpointer **array, gint *i)
{
 gint j;
    for (j=0;j<DEB_LINES;j++)       
        array[j] = (gpointer) malloc(50);
}

main (int argc, char *argv[])
{
  gint i, lin;
  gpointer **array;
  gint j = 0;
 GList *l = NULL;   
 GList *laux;      
           system("free");  
           array = g_malloc(DEB_LINES * sizeof(gchar *));
           create_list(array, &lin);
           printf ("\n---   Got memory  -------\n");           
	   system("free");  
	   if (argc == 2 && argv[1][0] == 'l') {
		   for ( i = 0; i < DEB_LINES; i++) 
		           l = g_list_prepend(l, array[i]);
		   printf ("\n---  All in list   -------\n");           
		   system("free");  
           }		   

           
  	   for ( i = 0; i < DEB_LINES; i++) {
                  free( array[i]);
	     }
  	   printf ("\n---   Freed memory?  -------\n");
	   system("free");  

  return 0;
}

If I just fill up the array the memory gets immediately freed:

but if I give te option to fill a glist with it it gets completely stuck.
