Yep.... I hope I can get up to speed here so I don't have to torture
everyone with these naive questions for too long! Thanks for replying.
The computer is a PentiumIII, with Mandrake Linux, and here's the gdb
output (I can't yet figure why this app is wanting a hostname, and it's

returning a null ptr).....
Program received signal SIGSEGV, Segmentation fault.
