Looks like the malloc pool is corrupt, as evidenced by free() calling
botch(), which is apparently trying to write to the console while it's
being closed.

Speaking of GUSI, I'm having no luck at all with it -- the FTP class seems
to hang in reads, then _Fread gets into a bad state where it's counting
down from 0xFFFFFFFF.  Oh well.
