Bug#425404: nscd: free's invalid pointer, causing calling program to abort
Package: nscd
Version: 2.3.6.ds1-13
Severity: important
So I get this output:
*** glibc detected *** free(): invalid pointer: 0x00002ae2a531bf80 ***
/usr/bin/da-backup: line 184: 360 Aborted (core dumped) rsync -varzH -e "ssh -i /root/.ssh/da_svn" --delete --delete-after --ignore-errors
/srv/svn.debian.org/svn/ root@backup.debian.org:irrelevant/
A backtrace of the core file shows:

So it appears the breakage is in nscd. Let me know you if there is any
more information I can supply.
