The test-suite failures appear to have been introduced in the patches for CVE-2014-0475 (2.11.1-0ubuntu7.14) and the patch for bindresvport (2.9-21). # objdump -DR build-tree/i386-libc/libc.s > libc.dis # egrep -n 'memmem@plt>' libc.dis 41049:000169d0 <memmem@plt>: 54050: 21063: e8 68 59 ff ff call 169d0 <memmem@plt> # egrep -B 50 -n 'call.*<memmem@plt>' libc.dis | egrep '<.*>:' 54009-00020fd0 <_nl_find_locale>: grep -rn memmem debian/patches/* debian/patches/any/cvs-issue12092.diff:2:Subject: [PATCH] Fix strstr and memmem algorithm. debian/patches/any/CVE-2014-0475.diff:43:+ if (__builtin_expect ((memmem (name, namelen, # egrep -n 'feof@plt>' libc.dis 41019:00016970 <feof@plt>: 315267: fa8dc: e8 8f c0 f1 ff call 16970 <feof@plt> # egrep -B 150 -n 'call.*<feof@plt>' libc.dis | egrep '<.*>:' 315131-000fa6c0 <bindresvport>: grep -rn feof debian/patches/* debian/patches/any/local-bindresvport_blacklist.diff:51:+ while (!feof (fp)) It appears feof() should be feof_unlocked().

I suspect a failure in debian/patches/any/CVE-2013-4357.diff nscd is installed and in use as a caching layer for openldap, which use used for passwd, group, and shadow but not services. Needless to say, a security update that causes a regression which makes 'apt-get' segfault is quite unfortunate.
