PAM/crond crashes with glibc 2.21-1

[Genes Lists <lists@xxxxxxxxxxxx>]

   Fully updated from testing repo. Bug filed:

      https://bugs.archlinux.org/task/43738


   After this glibc update I am now getting:

crond[952]: PAM unable to dlopen(/usr/lib/security/pam_unix.so): 
/usr/lib/libpthread.so.0: symbol __getrlimit, version GLIBC_PRIVATE not 
defined in file libc.so.6 with link time reference

crond[952]: PAM adding faulty module: /usr/lib/security/pam_unix.so
crond[952]: segfault at 59d6 ip 00000000000059d6 sp 00007fffea697798 
error 14 in crond[400000+d000]



   Perhaps packages need to be rebuilt against the new glibc?

Thanks
