Subject: Amiga E bug! (I'm pretty sure.)

    I seem to have found a bit of a bug in E. When trying to track
down memory loss in Dirj, through a whole lot of debug code, I managed to
track down the loss to a routine that frees a linked list of structures.
The structure is something like this.

OBJECT file
    next:LONG
    name:LONG     /* Name is ptr to String*/
    date:LONG    /* Date is ptr to datestamp */
    size:LONG /* Just a long */
ENDOBJECT

    Ok, name and date are allocated with String and New respectively.
The freeup routine uses Dispose on both of them, ie Dispose(file.name) ;
Dispose(file.date), then Dispose(file), which was also created with New().
Dispose frees up the datestamp, but not the filename. Now, supposedly all
memory is freed at the end of the program. This is not working. Every time
I free up a list, I lose all the string memory.
    Now, as a solution, to be fair to Wouter, I tried DisposeLink().
Which is really a dumb thing to have to do, I must say. It worked, but
obviously Strings' next fields start uninitialized because it was taking a
long time and still wasn't freeing all memory.
    The big kicker here is that all memory is allocated with E, and E
isn't freeing up all of it at the end, even with CleanUp(). This is really
screwing up my development, and is a really silly bug. If it wasn't for
the fact that I like Estrings, I would be using AllocRemember already.
    Wouter, any suggestions? Anyone?

    Please keep in mind that I do know what I am doing, and am not
just accusing E of my faults. If you like Wouter, I will send you the code
and you can check it yourself, but since this is Shareware in progress,
the only other people getting it are the beta testers.
