> Currently the trace tool traces all parameters to a method on entry to that method, and the return value on exit. However parameters passed by address or reference may be updated by the method and so are really output or inout parameters. These inout/output parameters should be traced on exit from the method. This is slightly harder than it looks since the entry trace must cache pointers and references to cope with code like...
> void func(int *p1) {
>   *p1 = 5;
>   p1 = new int;
>   *p1 = 6;
> }
> The caller of this method gets back 5 not 6.
