>Description:
Sometimes GDB doesn't find local variables. Here's the example of the code, where gdb fails:

   StateDescr  *sp = lm->states.addr;
   for (stateTable::iterator i = states.begin(); i != states.end(); sp++, i++) {
      StateDescr  *stp = i->second;
      int         len = strlen(stp->name) + 1;

      strcpy(cp_string, stp->name);
      sp->name = cp_string;
      sp->number = stp->number;
      sp->priority = stp->priority;
      sp->mask = stp->mask;
      cp_string += len;
      lm->strings.count++;
   }

If I set the breakpoint at "strcpy(cp_string, stp->name);": and try to print outr the "i" variable, gdb replies: "No symbol "i" in current context.".

The program is multi-threaded, but at the monent only single thread runs.
>How-To-Repeat:
I tried to reproduce the situation but regrettably it wouldn't appear in a simple programs.
