It seems that Debian 32-bit wheezy makes the linunx 32-bit biber binary segfault immediately and I need help tracking the issue down. The 64-bit linux biber binary works fine on Wheezy. If I install the ia32-libs package on wheezy, 32-bit biber segfaults so it's something to do with the wheezy 32-bit libc I think.
If you do "strace biber", you'll see that it dies while or just after reading an XML file which contains a lot of fairly obscure UTF-8 characters (it's the biber TeX macro <-> UTF-8 mapping data file). So, it's something to do with a conflict between libxml2 or perl's XML::LibXML library and libc I think (syslogs says that libc reports the segfault).
biber is using slightly older libxml2 that wheezy so perhaps there is a conflict with wheezy's 32-bit libc. As I say though, this doesnt' happen on 64-bit Wheezy.
