Don't know about your crashing problem, but the reason the library stack script
can't find the function handler in the main stack is that it's in the wrong
place in the message path. From the LC dictionary:
The start using command places a stack's script into the message path *after*
the current stack and before any objects in the backScripts. [emphasis added]
You could consider calling the function using the value() function -- look it
up.
put value(myFunction(x,y,z), stack "myMainStack") into functionOutput
