general protection fault gui runuserinterface

[Carrot826]

I currently have LabWindows 9.01 running on my computer.  I am writing a test automation program that uses GPIB to talk to several instruements.  I am having problems running my code because it will sometimes run into a general protection fault.  I suspect that it may have something to do with the GUI because the code crashes at the line where I call RunUserInterface ();  The crash report from windows is:

Thank you for your help.

Hello Carrot826,

Could you please follow the steps outlined here and post the resulting .dmp file to ftp://ftp.ni.com/incoming?  Also, if you could let us know what build version of CVI you are using (9.0.1.XXX), that will enable us to read the crash dump.  

Can you make any generalizations about what is going on when the program crashes?  Does it happen when waiting for user input, or immediately after some type of user interaction has occurred?  Is your application multi-threaded?  Any more description of the application you can give will also be helpful.

One final thing that would be helpful to include with the crash dump is a map file of your application, generated just prior to running it until it crashed. 

When you've got it up on the ftp site, let me know the name of the zip file you've uploaded, and I'll take a look.

Thanks!

NickB

I orginally began my project using labwindows 8.5 and then upgraded to 9.0.  I just reinstalled 8.5 and ran my code and saw that the function GetTableCellFromValue no longer returned the correction cell location.  The executable no longer crashes when I bulid using 8.5.  I orginally used the function to return the location of a cell with a particular value.  Can this functino cause a GUI memory leak?

Thanks.
