LabVIEW 13.0f2 crashes when cutting text from certain free labels on the block diagram

[GuenterMueller]

While revising the documentation of a VI, I faced a LabVIEW crash. I can reproduce it in LabVIEW 13.0f2 with the following code.  Can anyone confirm that cutting the content "def" from the free label and trying to paste it in the free label with "ghi" produces error 0xBC0BF185?

I cannot reproduce this issue by any other cut/paste between the free labels on the left-hand part of the BD.  The crash solely occurs when cutting "def" and trying to paste to "ghi".

I'm not reproducing it from the snipette. LabVIEW 2013.0f2x32 on Win7 enterprise. Heap Peek your copy, there is something insane with your label.

Whoops.... I take that back.

Thanks for confirming, Jeff. 

I didn't do any Heap Peak until now.  I did not expect any insane object because I actually created just the topmost free label.  The other instances were created by copy and paste from this free label.

Hi,

Heap Peak seems the way to use, to deal with this.

Hello all,

I looked into this, and it is more general than just the insanity in the label. I filed CAR 442743 for this behavior. It is a crash that can occur when cutting and pasting text between free labels in LabVIEW 2013 with the auto tool turned off. This is related to CAR 408955 (crash occurs when deleting a comment with auto tool turned off) which was fixed in the LabVIEW 2013 f1 Patch. This case was not covered by that fix and will be fixed in a future release. 

Thanks,
