How about posting some description and attaching some code to reproduce?
Created attachment 96756 [details] this is a short example of a C program that will segfault on amd64 this only crashes on amd64, it works fine on my athlon. it may be an issue for the glibc programmers... i've googled around a bit but i'm not sure where to go with it.
If you don't reopen after providing requested info, chances are noone will ever notice again.
your code sucks; read the strfry manpage you need to define _GNU_SOURCE
