GDB 4.18 and thread stack

[FLETERF]

 GDB 4.18 (LINUX Mandrake 7.1) seems to have a bug
 to report the stack of a thread having a page fault.
 When I run the below simple program, the commande "where"
 of GDB does not report the stack of the faulty thread.

 Does the GDB 5.0 fix this pb ?
 Does a previous version of 4.18 not contain this pb ?

#include <stdio.h>

void print_message_function( char *ptr );

main()
{
     pthread_t thread;
     char *message = "Hello World \n";

     print_message_function(message) ;

     pthread_create( &thread, NULL,(void *) &print_message_function, (void
*) NULL);

     while(1) ;
}

void print_message_function( char *ptr )
{
     if (ptr)
        printf("%s",ptr) ;
     else
        printf("%s ",  * ptr);   /* page fault here with NULL argument */
}
