Hi Yuri,

if the line number in the backtrace corresponds
to the upstream line number, then it's this:
int ftdi_transfer_data_done(struct ftdi_transfer_control *tc)
{
int ret;
struct timeval to = { 0, 0 };
>>> while (!tc->completed) <<<
I've analyzed the code paths and if it segfaults at "while (!tc->completed)",
either FreeBSD's libusb trashed the memory or something else trashed the memory.
It's rather unlikely it's a libftdi issue in ftdi_transfer_data_done().
Cheers,
Thomas
