There is no /etc/ld.so.nohwcap and:
wahiba:~# ldd /usr/bin/perl
linux-gate.so.1 => (0xffffe000)
libdl.so.2 => /lib/libdl.so.2 (0xb7edb000)
libm.so.6 => /lib/libm.so.6 (0xb7eb5000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb7e9e000)
libc.so.6 => /lib/libc.so.6 (0xb7d56000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7d28000)
/lib/ld-linux.so.2 (0xb7efc000)

There is a /etc/ld.so.nohwcap and:
wahiba:~# ldd /usr/bin/perl
linux-gate.so.1 => (0xffffe000)
libdl.so.2 => /lib/libdl.so.2 (0xb7f39000)
libm.so.6 => /lib/libm.so.6 (0xb7f13000)
libpthread.so.0 => /lib/libpthread.so.0 (0xb7efb000)
libc.so.6 => /lib/libc.so.6 (0xb7db3000)
libcrypt.so.1 => /lib/libcrypt.so.1 (0xb7d85000)
/lib/ld-linux.so.2 (0xb7f59000)
and if I manualy rm /etc/ld.so.nohwcap.
the configuration of libc6 works.
So the problem of segfault seems related to the presence
of /etc/ld.so.nohwcap.

and there is no /etc/ld.so.nohwcap
and after the dpkg --configure -a
the result is still the same
