All VIs containing MathScript cause a fatal crash after upgrading from 8.2 to 8.5... what gives?

[NIDave]

So I finally took the plunge and updated to 8.5 from 8.2 and now when I open a project that was previously done (as in ready for release this week 🙂 ) it causes a hard crash where LabVIEW closes completely.  I've looked and can't seem to find any others complaining of this.  My only option that works at this point is to have a coworker open all my VIs containing mathscript and delete the function with his 8.2 enviornment.  What could be causing this?  There has to be some simple answer...somewhere. 

Thanks in advance for all the help!

Dave

Hello Dave,

This is the first I've heard of such an issue.  Could you post one of your VIs that has a problem?

These VIs work fine for me under LV 8.2 and will no longer work under LV 8.5.  The first one is a call to our power supplies, the second uses the math formula node to verify that some color and luminance parameters are valid.

In the meantime I am stuck using a coworkers 8.2 development system with TS 3.5 to deploy which works with no issues.  When I try on my new system with 8.5 and TS 4.0 it crashes out.

Thanks for any help you can provide.

Hi NIDave,

I downloaded those VI's, and I was able to open them successfully in LabVIEW 8.5, but I did see some compile errors with the MathScript node.  The errors I saw have already been reported to R&D, and they are currently under investigation.  Currently the workaround is to continue using LabVIEW 8.2.  However, you seem to be experiencing a different issue, since you say that your LabVIEW crashes.  Can you give any more information on the crash?  Is there an error message? When rebooting LabVIEW, does it ask to do an investigation?

Kevin,

My LabVIEW crashes but it crashes cleanly.  There is no prompt for debug when I reopen it.  With LabVIEW open if I try to open those VIs LabVIEW simply starts loading them then disappears.  If I check for running processes it is not running.  Double clicking on the LV icon again opens the program and it looks as if it exited cleanly the last time.  Any other suggestions?  I remember back in my LV 7.1 days I added a string to the ini file that was supposed to help debugging an issue, could something like that aid here? 

Thanks,

Dave

Hi Dave,

I have had another engineer take a look at the files you posted, and he was unable to reproduce the issue as well.  Could you possibly post a project file showing the problem?  Also, if you create a very simple VI in 8.2 containing MathScript, will that also cause 8.5 to crash?

Would it be possible to test on another computer? I am not sure if you have access to another copy of LabVIEW 8.5, but that could be a very useful troubleshooting step as well.

Finally, can you make sure you have the LabVIEW investigate error enabled? In LabVIEW, navigate to Tools > Options, select the Debugging category, and ensure "Prompt to investigate internal errors on startup" is selected.

Kevin,

I'll do what I can with what I have.  Unfortunately I'm the guinea pig for 8.5 at work and no one else was going to install it until I can get all the bugs worked out.  I will see if I can get someone else to open the files on their copy of 8.5.  In the meantime I do have my PC as set to investigate internal errors on startup.  The last issue adding to this is that we wiped my PC clean of 8.2 and TS 3.5 to install this so I don't have access to build one in 8.2 until I can get someone else to do it for me.  I will reply ASAP.  Thanks again for your help.
