LabVIEW crash when saving from LV2012 to LV2011 with express VI and reopen in LV2012

[User002]

Hi all,

Preconditions:

1. Save the "Meas Angular Position-Buffered-Cont-Sync AI Sample Clk.vi" for a previous version of LabVIEW, in this case from LV2012 to LV2011
2. Reopen the LV2011 VI in LV2012 according to the steps below.

Steps to get it to crash:

1. Unzip Crash.zip
2. Open the "Meas Angular Position-Buffered-Cont-Sync AI Sample Clk.vi" and from there double-click (open) the "PulsedDerivative.vi" and from there double click the "Derivative dX/dt" express VI.
3. LabVIEW crashes!!

Alternatively when LabVIEW does not crash:

1. Unzip Crash.zip
2. Open "PulsedDerivative.vi"
3. Inside the VI double click the "Derivative dX/dt" express VI.
4. LabVIEW does not crash?

Some compiler bug?
