Dolphin X6 ToGo crash with dodgy .ERRORS file

> Hi,
>
> I've had several occurrences of a crash of my deployed app leaving a
> massive (~200Mb) .ERRORS file that has some kind of dodgy data in it.
> When trying to open the file, it seems to have multiple start-of-file
> and end-of-file characters in it, as the reader thinks it is at the
> start/end throughout the file.
>
> This is DX6, the same app has never done this in D5.
>
> The app seems to be crashing on a divide-by-zero error, with some
> strange references of a bad array [00000000]. Trying to figure out
> what's going on I got the suspicion it is in the message forwarding.
> I've overridden #doesNotUnderstand: to forward messages of a wrapper to
> the wrapped object. Now the bad array gets created when the message
> (which doesn't have any arguments) gets sent around. As the Array has
> seen changes in DX6 to support immutable arrays, I can imagine the
> Message class>>selector: message might be causing the problem, as that
> creates an immutable array for the arguments.
>
> See enclosed for an extract of the error log (most of this is repeated
> umpteen times).
>
> Can anybody shed some light on this?
>
> Thanks,
>
