<pre>
    I'm seeing a test case (test_ldap) for the adcli-0.9.2 Fedora package segfaulting with current main (342c8db381129e908116f1059e97d235b62bcaf2).  I've bisected the failure to commit 7954a0514ba7de40dba6c598af830fd1b7a8bf0c

The backtrace for the segfault is:

```

```

The source code for the project is [here](https://gitlab.freedesktop.org/realmd/adcli/-/tree/0.9.2?ref_type=tags)

It seems like it could be a case of UB, but I'm not sure.  What other information would be helpful for reproducing?
