strtok, bus error

i'm trying to do pretty simple replacement using strtok.
but it looks like i have missed some subtle difference between the two following 
  
  char src[]  = "hello world #";
  char *other = "hello world #";

because if i use "char * other" with strtok it fails with bus error but i use src it works, don't understand what's the difference.

here's the code for strtok.
     char delims[] = "#";
     char *result = NULL;
     // this works 
     result = strtok( src, delims );
     // this doesnot work and give a bus error
     // result = strtok(other, delims);
     while( result != NULL ) {
         printf( "result is \"%s\"\n", result );
         result = strtok( NULL, delims );
     }

what am i missing here ? i thought both way of declaration(mentioned above ) were the same apparently the r not, whats the diff ?

any insight would be appreciated, TIA!
