Wanted to port some of my older LV panels to 8.5. I noticed that LabView would generate the following message when attempting to load one of my panels:"Unhandled exception at 0x007513e0 in LabVIEW.exe: 0xC0000005: Access violation reading location 0x00000000" The following is a snippit of code from the debugger:007513B0 aaa007513B1 adc esi,dword ptr [ebp]007513B4 bound edx,qword ptr [ebx]007513B6 jne 007513B8007513B8 jnp 007513CD007513BA jne 007513BC007513BC xchg eax,esp007513BD adc esi,dword ptr [ebp]007513C0 xor ecx,ecx007513C2 xor eax,eax007513C4 test edx,edx007513C6 je 00751461007513CC mov eax,dword ptr [edx+4]007513CF test eax,eax007513D1 push esi007513D2 mov esi,dword ptr [edx]007513D4 jle 0075145B007513DA mov edx,dword ptr [edx+8]007513DD push edi007513DE mov edi,eax007513E0 mov al,byte ptr [esi] <<<<************************************************ Dies here007513E2 cmp al,2007513E4 jne 007513EB007513E6 or ecx,4007513E9 jmp 00751412007513EB cmp al,5 Panels like this one are mid sized, containing 10 - 20 sub VIs. I stripped the panel down to try and find what exactly was causing LV 8.5 to crash. It turns out to be the digital graph. I have attached a very simple panel that just contains the digital graph with nothing wired to it. If you try to run this in 8.5 I am guessing it will cause the problem. I tried it on a few PCs and get the same results.

digital graph causes exception in 8.5

lecroy,

Thank you for your diligent work on this one! This was reported to R&D (CAR ID # 130365) for further investigation. Looks like you've done all you can on this one.
