Bug: Data Types with Large Type Descriptors crash Variant To Flattened String

[Jim_Kring]

This is a cross post.

The data type of the control in the attached VI (Variant To Flattened String Crash.vi) has a type descriptor that cannot be represented using the I16 "7.x" type descriptor array.

We can see this when we try to read the type descriptor as shown below.  We get an edit time error (you probably won't see the broken run arrow until you hit the run button).

If you try to convert to variant first and then read the type descriptor (and bypass LabVIEW's edit-time type checking) you'll get a hard crash (LabVIEW just disappears), as shown below.

Sorry Everyone,

I meant to post this in the LabVIEW forum, but accidentally posted it to the BreakPoint forum.

I've created a new thread on the LabVIEW forum that points to this one.

Thanks,
