Hi, I used ftdi_usb_find_all() in my own program, which eposed a memory leak, so I tested examples/find_all.c and it leaks, too (valgrind output below). Is this the leak Uwe mentioned here http://developer.intra2net.com/mailarchive/html/libftdi/2010/msg00213.html ? If so is there a patch I've overlooked? I'm using a fresh libftdi-1.0/master checkout from today.
