This is so because there is a read just after the connect which is
logged

IMO if the problem is triggereddepends on who compiled the
setup.exe. The pointers net_ftp_user and net_ftp_passwd are not
zeroed in the code so it's up to the compiler if these are
set to zero or just some random garbage. For example the MS compiler
sets all unitialized variables to zero if you're building debug
version of an app and leaves these as is if you're building release 
unless you specify otherwise explicitly with an compiler option.
