Silly assignment question

Hi,
  Silly question time.

The following C program would seem to be ok...

#include <stdlib.h>

void assign(char *a, char **b)
{
  *b = a;
}


int main() {
  char *a = "test";
  char *b = NULL; 
    
  assign(a,&b);
  puts(a);
  puts(b);
  return 0;
}



while the following root sequenence isn't.

root [0] .L qq3.C
root [1] char *a = "test"
root [2] char *b
root [3] b
(char* 0x0)""
root [4] a
(char* 0x40aad8)"test"
root [5] assign (a,&b)

 *** Break *** segmentation violation


where qq3.C is:

void assign(char *a, char **b)
{
  *b = a;
}



Could someone point out what I'm doing wrong?   Sorry if this is simple,
I just don't see it :-)

Thanks!

bruce
