Hi, I can confirm this bug. Using a file with 5 new users I get the following error:
# newusers 5users.csv *** Error in `newusers': double free or corruption (!prev): 0x0000000001ae2d10 *** Aborted A curious detail: if the first 4 users are already created and I run newusers, the 5th one is added without problems. If I have 6 users in the file and the first 5 users are already created the 6th one is added without problems. And so on. $ dpkg -s passwd | grep 'Version' Version: 1:4.2-3.1
