That line refers to an if statement that compares an UInt and Word.
So its crashing when comparing a UInt32 vs. UInt16. How does the compiler
promote/demote in this situation? if(UInt32 < UInt16) I would imagine it
should work up to 2^(16) or at least 2^(15) and not 2^(14)
I would be interested in the explanation also, I ran into something similar
about a year ago and had to rewrite the app to reduce the # of records
allowed.
