Firstly, StrLen returns an Int16, which has a max value of 32767. If your
length is in fact over that limit it is conceivable that it might return the
signed equivalent (in memory) which is -15136 (0xC4E0). When you typecast
this to the UInt32, it is probably sign-extending this to 4294952160
(0xFFFFC4E0). This doesn't explain your figure of 4294952512, though.
