Crash LV 12.0f3

[ouadji]

With this code, LV 2012 f3 crashes.

Can anyone confirm this behavior ? (before reporting it as a bug)

my first post

[Norbert_B]

Can you please state your OS and if this is 32bit or 64bit LV?

thanks,

Norbert

Yes, for me it crashes too.

(thank you Harlequinade for the test)

ouadji :

Windows XP pro sp3 (32bits) - LV 2012 0f3 32bits

error code : 0x80000003 (STATUS_BREAKPOINT)

with syser (kernel debugger) in the background, when LV crashes, syser handles the crash and I see a breakpoint INT3 (0xCC)

[Norbert_B]

Since the issue reproduces on several machines, i created CAR #392545 for it.

EDIT: The crash is connected to modifying the Offset with altering values and re-setting the Mode to anything other than "No Change" continuously. My test revealed that setting the Mode once before entering the TL does not lead to the crash. You should try and verify this.

like this ?

for me, this code (below) crashes LV too.

[Norbert_B]

Remove writing the Mode from within the TL. Just modify the Offset.

"just modify the offset ..." ...

yes but look at this :

http://zone.ni.com/reference/en-XX/help/371361J-01/lvconcepts/con_change_tsnodes_dynam/

NOTE : If you dynamically change the offset of a Timed Loop by wiring a value to the Offset input of the Right Data node,

you also must specify a mode with the Mode input of the Right Data node.

[Norbert_B]

Hm, please give it try nevertheless. I received no error, but i didn't test if the modified offset took effect.....

So possibly, my offset was not "updated" or the documentation is incorrect.

Norbert

[ouadji]

without writing the mode within the Timed Loop ... (like below)

LV does not crash ... but the offset is not updated.
