I found the error. I had copied most of the VI from a similar one.
The VI consists of a loop for maintaining an array of objects
representing power supplies, which are in a different class hierarchy
from the VI I copied the block diagram from (which dealt with
oscilloscopes). There was one sub VI that I had forgotten to replace
with its equivalent from the power supply classes, so I had a VI
loading a scope from a file and sticking it into an array of power
supplies. I don't know if it's a bug or a known limitation of LabVIEW's
type system, but the wire from this sub VI to the "insert into array"
function was not shown as broken; instead, I got the above compile
error.
I'll see if I can reproduce the problem and post a
simple example VI here, though it might be hard since it depends on
having at least two different classes.
Edit: By the way, LabVIEW 8.5.1 on Windows XP.
