I have another issue with the same technique, maybe it is related so i add it here:

I have setup a directive with 2 keys for an user, with option: flush the authorized keys file before updating : yes

After a run i can onserve following :

• The directive is "repaired".
• In the .ssh/authorized_keys i observe:

1. the first key is duplicated after each run, until i have 3 times te line with the first key;
2. the second keys is prepended by spaces.

ssh-rsa AAAAAA aaaaaa
ssh-rsa AAAAAA aaaaaa
ssh-rsa AAAAAA aaaaaa
                ssh-rsa BBBBBB bbbbbb

NB: With option "Do you want to flush the authorized keys file before updating: No", then the first key is duplicated ad nauseam.

Maybe important: in this directive, i have 3 ssh keys, and the impacted key item is "SSH key #3". This makes situation similar to #5561.

Update: the fact that key is "SSH key #3" is important. If i break the ssh-key directive into 3 different directives, then the duplication of the key disappears.

I can definitively reproduce the issue
If the key is too long ( roughly around the 1K length, then the class definition segfault)
We need to update the technique to not use such long classes
