LabVIEW 8.6.1 crashes when copying a linked tunnel.

[jlokanis]

If you make a linked tunnel and then try to copy it with a ctrl drag operation, LabVIEW will crash.  See attached VI.

Yes, this looks like a bug....

I reported it here for reference.

Yep, I recreated it and it has been filed. CAR 168930.

Hi Jeff,

Please compare that bug with CAR# "163173" that I believe I reported. THe description was "Copy Shift Registers, Terminals, and Wires causes crash".

Same or different?

Hmm, interesting, Ben. To recreate the issue above, I did select the tunnels, shift registers, and wires like your CAR states. With the VI posted here, that works with the Linked Tunnels but not with the regular tunnels. Have you tried the attached VI above, Ben?

What are you guys selecting to cause the original crash in this thread?

No, I have a real job.

I posted the example to the AE I was working with, got him to recreate the crash and my final words where "Hint, I have linked those tunnels.".

Take care,

Ben

[JeffL]

Haha, fair enough.

Yeah, they might be related. I have made note of the new CAR in the old.

Can you guys above point out what exactly you're copying to cause the crash?

I think the key thing to copy is the linked tunnel.  I came across this while building up a state machine framework and was trying out the new linked tunnel feature.  If you don't link the tunnels, they copy fine.

• Select linked tunnel and ctrl+drag: we get the + cursor, but nothing actually happens. No copy, no crash.
• Same if we select and lined tunnels and the SR. No copy, no crash.
• Same if we select the linked tunnels, the SR, and the boolean diagram constant and do a ctrl+drag. No copy, no crash.
• If we select the linked tunnel, the SR, and the wires connecting them and do a ctrl+drag, we get the crash.

There are of course many more combinations, but the above is what I tried.

For those tracking CAR numbers, I've closed CAR 168930 as duplicate of 163173 and updated the active CAR to explicitly state Linked Tunnels.
