OLC-Plusv2.1a + Copyover

From: Ryan Guthrie (guthrie@henge.com)

I recently decided to start my mud over to update some old stuff and add
some new features.  Last time i did this(for another person) I ran into
this same problem.  That is: When I do a copyover, it does it and brings
me back to the prompt, but whatever i type in next crashed the mud.  As
far as i can remember, the gdb information was of no relevance, but here
it is anyways.

1849          if (!(failed_subst = perform_subst(t, t->last_input, tmp)))
1850            strcpy(t->last_input, tmp);
1851        } else {
1852          strcpy(t->last_input, tmp);
1853          if (t->history[t->history_pos])
1854            free(t->history[t->history_pos]);       /* Clear the old
line. */
1855          t->history[t->history_pos] = str_dup(tmp);        /* Save
the new. */
1856          if (++t->history_pos >= HISTORY_SIZE)     /* Wrap to top. */
1857            t->history_pos = 0;

I remember the fix being quite simple(as in taking a line from one
function and pasting it into another).  I have comparted my old mud with
my new mud but the answer is alluding me. Help would be appricated.
