Thanks Henry and Sven. I suspect that both FPP and Valgrind will end up 
being a substantial amount of work for a one-off problem... FPP in 
particular since it requires Lazarus to build but I'm trying to debug 
part of the Lazarus build process (bug 0018600).

I'm about to start inserting debug messages. I might be some time.
