After a system update in xenial on my notebook, I was unable to login through GDM and tty. After some investigation, I found a probable cause for this problem: when logging in from getty using /bin/login, the program would abort. Here comes a example for debugging, I moved /bin/login to /bin/login.real, and make /bin/login a bash script:
$ cat /bin/login
#!/bin/bash
export MALLOC_CHECK_=1
/bin/login.real "$@"
$ file /bin/login.real
/bin/login.real: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.32, BuildID[sha1]=e5d2ebf80be6b1a4f2fc0073e7857ccbe3b875a1, stripped
