Strange. I did some work at this code. I found one thing only which will
be x86_64 specific. In pacman.c there is a callback point (as i remember
it was in pacman.c :) ) which got some : (long)log_progress()
definition.

Actually in download.c (and in.h) the log_progress function is 

int log_progress(...)

I tried to change from int -> long in download.c and .h to see that
cause the problem or not. No, that wasnt :) (as you know on x86_64 int
and long matters, because of size difference)

So the problem still exists. I catched up some backtrace with the not
debug binary pacman and seems that it segfaults at FtpRead() function.

That is strange too. 

A notice for this, the main progressbar moves to some ~5 or 10% and
crashing after that. So it will be some magic buffer overrun
somewhere :S 

Still i will work on it (cause i got x86_64 machine) and maybe see what
i can do.
