Memory leak in Convolution

[GregSands]

The attached VI shows a memory leak in the Convolution routine in LabVIEW 8.6.1.  There is no memory leak in 8.2.1 - I have no other versions to test it on.

Ouch!

Yes, something is terribly wrong in 8.6.1 with this function.

Hi Greg,

This behavior has been reported to R&D (#128859).  Note that the leak only happens when the size is set to size X.  Thank you for reporting this.

Best Regards,

Looks like the problem is solved on 2009?

Yes, this issue has been fixed in LabVIEW-2009

You can always check the Bug Fix list to see if a particular CAR has been fixed.

So...I pretty much just have to live with this in 8.6?

Hi Tim,

Since we are no longer developing for LabVIEW 8.6, this is going to be something you need to either workaround, or update to 2009.  The leak only occurs when you set the size to "Size X".  And, it has been fixed for 2009.

Turns out a workaround wasn't very hard to come up with using Full instead of X.  Thanks

I just got bit by this bug in 8.5.1. :manmad:  It crashed LabVIEW a couple of times this morning before I could determine what was going on.

I'll use the workaround suggested.

Thanks!
