XControl Init with LVClass Constant Crashes

[jdunham]

My XControl was crashing on me the other day, and I isolated the cause as an lvclass constant in the init case.  Strangely, it only crashes if the xcontrol is dropped from the palettes with "Select a Control...".  If you drag and drop the XControl from the Windows Explorer onto a front panel, it doesn't crash. Example is attached.

I haven't yet gotten any CAR# from NI, but I'll post it here if I get one.

I was able to reproduce this behavior, and have filed a CAR #258105.  I want to thank you for your detailed description of how to reproduce this error.  It is descriptions like these that allow us to easily reproduce errors, and start the investigation process.
