V1.0.0 crash avr + 74HC4051

My students are using the 4051 mux, but I seems to create crashes with avr core after connecting the logic analzyer or a scope.
An example of such a circuit is attached.

Used simulide Version: V1.0.0 WIN10 (and also available in R768)

Situation:

1. open simulide (WIN10)
   
2. load crashAVR.sim1
   
3. run (without any hex flashed)
   
4. stop
   
5. connect CH1 of the logic analyzer to Z of the 74HC4051
   
6. run (without any hex flashed)
   
7. crash
   

It seems that any (new) connection between scope/analyzer and 74HC4051 generates a crash... Sometimes the error is also shown in a windows error message (illegal memory access), see attached jpg.

Thanks.
I will have a look.

EDIT: As an alternative, just use an analog mux, it's exactly the same.
Not sure if it will also crash...

(I somehow missed the new version R779.
I just tested it, the bug is there too.)

The analog mux also crashes...

The analog mux also crashe

Now we now where is the problem...

Issue solved at Rev 786.
