Ok, all well and good.. but then how does the heaptrace run?

In addition, if I comment out the Extractxxx() call then it always cleanly frees it's memory, halt 
or no.

I only use Halt() in the event of a fatal error in any case here, but I'm stumped with this string 
not being freed in my app when I'm _not_ using halt.

I was using the unix units before with BaseDir() and Dirname() without issue, but I needed to go 
cross-platform so I converted to the Sysutils calls ExtractXXX(), which is when the problem arose.
