LV crashes when activating the broken arrow

[mekman]

Hi,

I'm using LV 8.2 Full Development system. All the sudden, when the broken arrow appeared I could

not activating it in order to get a list of syntax errors, as usual. Instead LV simply crashes. I've tried to copy, the VI,

making a new VI and copy the contents into the new VI. All with the same result. The VI is rather big (3.5 Mb).

If I clear most of the code, LV seems to work again. I have not been able to figure out wheather there is a part

of my code that messes things up.

As I can not use the debugging I'm in trouble.

Any idea ? Anyone ?

Regards,

Mikael

Have you tried to just go to "Menu...View...Error List" (or ctrl+l)?

I would submit the VI in question to NI support. Is there anything unusual in your code, e.g. lots of third party DLLs, etc?

I trouble shot a bug in LV 7.1 or earlier that had the same behaviour.

If memory serves me, it had to do with a "bundle" function.

I can not say that what you are seeing is what I saw so the best I can do is sugest "half-splitting".

Working form a copy...

Delete half.

If it works now, you deleted the problem, go back to the backup and delete half of the half...

I hope that helps,

I can't offer much solace, save for the fact that you are not alone.  A colleague of mine recently upgraded from 8.0.1 to 8.2, and a project (specifically the top level vi) was showing the same behaviour as you described.  I had not seen this problem, and he asked if I could try the VI on my machine, with the same result (complete LV crash).

He spoke to NI for a while on the phone, trying various things like driver reinstallations, LV reinstallation, etc.  So far he hasn't gotten it working.  He's been reassigned to something else for the next little while so he cannot keep trying to solve the problem.

I'll post again here if I get any new info.  If you find the problem, please let me know as it was frustrating my colleague quite a bit.

A WORK AROUND SOLUTION

The work-around suggested by Altenbach seems to work fine.

Thank You!

So simple and straight forward that it did not even cross my mind.

However, I can still not push the broken arrow but the error list now displays

without LV crashes. And thats what I need.

My only worry is that this fatal bug in the LV system is still there, and it can

anytime blaste my several-year long project in to the twilight zone.
